Customers with crowded mailboxes now prefer to hear from brands via quick and short SMS. In fact, the latest data seems to confirm this: every two in five consumers are open to hearing from brands through SMS. 

Surprisingly, consumers from ages 25 to 54 prefer to communicate with brands via SMS, even over email. So, undoubtedly, SMS is a growing marketing channel. 

But the question is, how do you make the most out of it? 

Sure, you can grow your SMS list now by encouraging customers to sign up. The Internet will also (t)sell you some other shortcuts to buy phone numbers. However, the Telephone Consumer Protection Act (TCPA) prohibits companies from buying phone numbers—and you may incur substantial penalties.  

What if we tell you—there is a way you can collect phone numbers, being totally compliant with regulations, by getting consent from customers. 

This article will discuss some tried-and-tested strategies on how to get people’s phone numbers for SMS marketing. 

10 ways to collect phone numbers

Here are the top 10 ways to collect phone numbers compliantly from customers:

1. Include a sign-up form on the website with offers

One simple step is to include a sign-up form on your website to collect phone numbers. You can highlight the benefit of signing up to the SMS list. 

For instance, you can give 15% off on subscribing to an SMS list or promise exclusive offers. You can create a simple form on your website and connect it with SMS or an omnichannel marketing platform that collects all the data.  

For example, Ice Jewellery, an accessories brand, added a sign-up form on your site to collect their website, and customers would receive exclusive offers via SMS.

2. Get opt-in on the order page

Another way to boost SMS marketing is to get opt-in on the order page. This is a low-effort step for customers, who have to just tick a box while placing an order.

This strategy reduces the friction. You can add a small checkbox on the checkout page and a small note highlighting the benefits of signing up for the SMS list. It could be early access to new stock, exclusive perks, and more.

For example, Domino's asks customers to choose at the checkout page where they would like to get text or email offers.

3. Promote on social media

You can also create exciting posts or stories on social media, providing links to join the SMS list. Highlight the exclusive benefits of subscribing to your SMS list, such as early access to sales, special discounts, or VIP-only offers. 

Petite Studio, a clothing brand, launched a VIP SMS list on social media offering 15% off. Customers who join the SMS list will get style tips and early access to sales.

AOPSIA, a clothing brand, promotes its latest collection on social media by promising early access to SMS subscribers.

4. Run contests or giveaways

Go ahead and run contests or giveaways exclusive to the SMS list subscribers. It gives incentives to customers to join the SMS list.

For instance, Carnegie Deli ran a Valentine’s Day giveaway for its SMS list subscribers and posted about it to encourage followers to join the list. 

5. Promote via collaborations

This step is closely related to the strategy above. Promote such contests or giveaways by collaborating with influencers for wider reach. Find influencers in your niche with a highly engaged audience with whom you can collaborate to promote your SMS list/contest/giveaway. 

Check if the influencer's content and brand image resonates with your brand values and messaging before collaborating.

6. Set up a short code or long code

Other than providing the link to join, you can also set up a short code for your business. A short code is a 5 to 6-digit phone number used in SMS marketing. 

For instance, 12345 can be a short code, and customers can text ‘JOIN’ to 12345 to join the SMS marketing list. Short codes are often shared across companies and used for mass promotion. 

Alternatively, focus on creating a long code. Long codes are 10-digit numbers, similar to regular phone numbers. These long codes are not so common for mass promotion but are usually helpful for two-way communication. They are simple to set up and get approved faster. Having these dedicated numbers brings more trust in customers. 

RIPit, a performance gear brand, promoted its SMS marketing deals on social media. Customers have to message “JOIN” to their long code for exclusive discounts. 

7. Add a CTA on product delivery email

Another underrated way to promote an SMS marketing list is via product delivery emails. Add a quick note about the SMS list at the end of the email. 

For instance, add “Join the VIP SMS list for future offers” with instructions in your email to keep customers hooked to your brand. 

8. Promote via newsletter

You can promote your SMS marketing via your regular newsletter. Create a compelling graphic to promote the benefits of joining the SMS list and provide clear instructions on how to join.

For instance, GoPro, an electronic manufacturing brand, offers 15% off and special perks on joining the SMS list. They promoted these benefits via their newsletter. 

9. Get opt-in at the point of sale

If you have a physical store, you can also ask customers at the checkout counter if they want to opt in for SMS to get offers. Here is where the omnichannel platform helps you. 

Having a single platform that stores customer data and runs marketing will help you run promotions with ease. 

For example, Tom’s of Maine, a personal care brand, encourages customers to join SMS campaigns by texting “prebiotic” to a listed number.

10. Get opt-in via website chat

Use website chat as a medium to sign up for SMS marketing by sending a quick note like below:

"Before you go, join our SMS list for exclusive offers and early access to the latest collection! Enter your phone number, and we'll send you a special discount code."

6 Best practices to get more opt-in from customers

Follow the 6 best practices below to get maximum engagement from customers:

1. Always ask permission before adding to the SMS list

Never add any customer number to your SMS list without seeking permission. It looks like spam and increases your chances of being blocked. Use any of the techniques mentioned above to get customers' opt-in.

2. Keep the opt-in instructions simple

Make it easy for customers to sign up for your list. Provide a direct link for SMS sign-up with simple instructions.

3. Be transparent on purpose

When you ask customers to share their number, ensure they know what they are signing up for. This precaution will help you get a more engaged audience for your SMS marketing efforts.

4. Always give an opt-out option

Provide an opt-out option in every SMS so they can opt out when the messages are no longer relevant to them. It creates a negative experience for customers if they are unable to subscribe easily.

5. Offer incentives on opt-in

Highlight the benefits of signing up for an SMS list for customers. With every brand wanting a share of their time, customers need a solid reason to share their phone number.  

6. Follow data protection regulations

As you are collecting customer information, ensure you are following all data protection regulations such as The General Data Protection Regulation (GDPR), California Consumer Privacy Act (CCPA), and more.

When to look for a Google Voice alternative

Google Voice can be a great fit for solopreneurs, but as your business grows, it might not meet all your needs. Here’s why you might want to explore the best alternatives to Google Voice. 

Expand your VoIP’s feature set

Alternatives to Google Voice offer advanced features such as custom call routing, IVR, detailed call insights, or integrations with CRM systems. These features can enhance your communication strategies and improve customer experience.

Manage high call volumes effectively

Integrate with other business tools easily

Effortlessly syncing your VoIP with your CRM or automating workflows is crucial for smooth operations. Unfortunately, Google Voice doesn’t integrate with many CRM tools.

Research shows that most consumers want to receive text messages from brands they know and love. In fact, according to Yotpo, more than 80% of shoppers are already signed up to receive text messages from at least one brand. 

Despite the data clearly indicating that your brand can and should take advantage of SMS marketing, you still explicitly need your customers' permission to text them. Opt-in and opt-out regulations dictate how individuals give or withhold consent for their personal information to be collected, used, or shared. 

Opt-in and opt-out regulations differ from region to region. Some may mandate opt-in for certain data types, while others may allow opt-out. In this guide, we’ll outline the key tenets of opt-in rules, share the most widely applicable best practices, and suggest the best way to manage these permissions so your company remains compliant. 

Why businesses must ask for opt-in permission

There are several reasons why businesses must ask their customers for opt-in permission. First and foremost, it’s a legal requirement in many places. For instance, the General Data Protection Regulation (GDPR) in the European Union mandates opt-in consent for certain types of data processing. Under GDPR, consent must be freely given, specific, informed, and unambiguous. Failing to obtain proper opt-in consent can lead to significant fines and legal issues for businesses.

Opt-in and opt-out options also help businesses demonstrate respect for user privacy and build customer trust. These permissions give users control over their personal information, which can strengthen a company’s reputation. Opt-in models require businesses to clearly explain:

• What data is being collected
• How it will be used
• Who it may be shared with
• The user's rights regarding their data

This ensures users make informed decisions about sharing their information.

Finally, and perhaps most importantly, opt-in/opt-out permissions minimize the risk of a privacy breach. By only processing data from customers who have explicitly granted permission to do so, companies can reduce their exposure to possible privacy violations. 

What are the opt-in and opt-out requirements?

Opt-in and opt-out requirements describe someone’s actions concerning their personal data when accessing an app, website, or marketing campaign. For example, someone could choose to accept cookies, stop receiving text messages, or share their personal information to receive a newsletter. 

Opt-in and opt-out requirements differ in their approach to obtaining consent from individuals regarding the collection and use of their personal data. Opt-in consent requires individuals to actively and explicitly agree before any processing occurs. 

Opt-out requirements assume consent by default, meaning the user has to take action if they do not want their data collected or used. The table below shows a high-level comparison between opt-in/opt-out approaches.

There are certain legal requirements to be aware of as you set up your opt-in/opt-out collections process. GDPR isn’t the only regulation governing consumer privacy with data processing consent requirements. Many countries, including EU member states, Canada, and Australia, require opt-in consent for email marketing. The United States, under the CAN-SPAM Act, allows opt-out approaches for commercial emails.

Rules aren’t limited to governmental bodies, either. Gmail and Yahoo have also issued new email sender guidelines which require every email to have visible and accessible unsubscribe options. 

Opt-in: a deeper dive

For businesses, the level of opt-in required varies based on the type of message being sent. The CTIA, a trade association for the U.S. wireless communications industry, outlines three main categories:

Promotional messages

Promotional messages require explicit written consent from customers before you can send them. 

A promotional SMS marketing message encourages customers to take action, such as purchasing, attending an event, or engaging with a product. Examples include:

• Product recommendations
• Event announcements
• Seasonal offers

Informational messages

Informational messages require written or verbal permission from customers prior to sending. 

An informational message is an update related to a customer's account or their relationship with the business. These messages include:

• Account notifications
• Loyalty program reminders
• Appointment confirmations
• Welcome messages

Conversational Messages

Conversational messages do not require explicit opt-in consent. These types of messages are one-on-one exchanges between a business and a customer, initiated by the customer. As such, the customer's initial outreach implies consent for that specific conversation. However, this doesn't grant permission for marketing messages or discussions on unrelated topics.

Here are some more specific opt-in and opt-out scenarios to consider. 

Double opt-ins 

A double opt-in is one in which a user signs up for an email marketing list or to receive SMS, and then a message (email or text) is sent to the user to click and confirm the subscription. The confirmation click is required for the user to receive future communications. 

The double opt-in confirmation method not only helps reduce the risk of spam emails or fake numbers but it also reduces instances of bots signing up for your communications. This added step ensures that all your recipients are real people who genuinely want to hear from your company. This translates to higher engagement rates and lower costs. 

Opt-in for websites, social media, and email 

Opt-in approaches for websites, social media, and email share some common principles, but also have platform-specific requirements. 

Websites must get explicit opt-in consent before using non-essential cookies. The easiest way to get this consent is to show a banner or pop-up when a user first enters the site. You may also want to include opt-in consent to use analytics tools, depending on your location. 

Social media platforms also generally rely on opt-in consent for data collection and storage, but the platform itself will handle that for you. For example, a Facebook user agrees to Meta’s terms of service and privacy policies when creating an account. You don’t have to ask a second time when you view your business profile’s analytics. 

However, some platforms may require additional opt-in consent for certain ad targeting or data-sharing scenarios. Facebook requires explicit opt-in for some sensitive ad categories.

Opt-in for email marketing and SMS 

Email and SMS campaigns have their own set of rules that your business needs to know. You must get explicit consent before sending any marketing messages via email or SMS. For email, consent is required but can be implied in some cases (such as if the user has an existing business relationship). 

SMS has one additional requirement. Your SMS messages must include clear disclosure of message frequency, potential carrier charges, and how to opt out if the user no longer wishes to receive messages from your business. Follow these best practices when designing your SMS opt-in approach: 

• Keep initial messages short (under 160 characters)
• Clearly state your company name and purpose of messages
• Provide immediate value to the recipient (e.g. welcome offer)
• Make opting out easy with clear instructions

Your email campaigns must include your company’s physical address, as well as an unsubscribe mechanism. Like SMS, try to make the sign-up process simple and user-friendly. 

Offer a preference center to manage subscriptions and set clear expectations about email content and frequency. 

How to incentivize opt-ins

Now that you know the guardrails governing opt-ins, how can you encourage your audience to sign up for and continue receiving your SMS marketing?

First and foremost, as the saying goes, you have to give something to get something. Give your audience a clear reason for subscribing to your SMS messaging list, such as a discount, early access to sales, or personalized shopping recommendations. In the process, set clear expectations: let the customer know how often they can expect to hear from you, as well as what kind of texts they will be receiving (for instance, order updates, appointment reminders, or something else). 

Next, make it easy to say yes. Use keywords for easy text-to-join options; for example, a pet supplies subscription box could ask customers to text “WOOF123” to a short code used by the brand. Any forms that need to be filled out should be optimized for mobile. Think about your sign-up process, too. 

Finally, to retain customers, make sure you stick to your cadence and continue offering value in your SMS marketing outreach. If you start to see opt-out rates creep up, check on your analytics to make sure there are no issues with your delivery. Then, consider whether your SMS messaging delivers your audience something unique and consistent with the rest of your marketing efforts. 

Opt-in and opt-out best practices 

Crafting effective opt-in prompts is more than just a formality. It's a strategic decision that can foster a loyal, engaged audience. By adhering to best practices, you'll enhance your customer experience, ensure compliance with data privacy laws, and build trust. Follow these best practices to make it easy for your audience to control how much they share with your business. 

1. Don’t pre-check the opt-in box. Some forms are set up so that the user has to opt out and uncheck a box to avoid receiving emails. It’s a sneaky way for a brand to collect user information since most people don’t realize they must uncheck the box. Clearly, this does not foster trust with your audience. 
2. Use a CAPTCHA or OTP to secure your sign-up form. A CAPTCHA can help prevent bots from signing up for your SMS list. Screen out bad actors to prevent cost overruns and protect your subscriber list.
3. Maintain your list regularly. Update your contact lists regularly to remove unresponsive subscribers and invalid numbers. Cleaning up your list ensures you are only messaging with engaged users and not spending your budget sending SMS to those who won’t respond. 
4. Use double opt-in. Employing a double opt-in approach can significantly improve your campaign results. When users opt-in twice, you can be assured that they definitely want to hear from and engage with your brand. This leads to better quality and higher performance. 
5. Make your opt-in message crystal clear. Your SMS opt-in form must specifically mention SMS as the communication channel. In the US, 10DLC compliance mandates that you mention SMS in your opt-in form. For example, your opt-in form could read, “Check this box to opt-in to receive SMS text messages from (Your Company Name). Standard rates and data may apply. Reply STOP to opt out."

Ultimately, the goal is clear, simple communication with your SMS subscriber list. These tools can help you manage opt-in to achieve that outcome.

Choosing the right API for 2FA provider for your business needs

Clearly, the range of APIs on the market varies widely. How can you tell which one best meets your needs? 

If choosing an API for a 2FA provider feels daunting, here are three steps to help: 

1. Align the API’s capabilities with your business goals: When choosing a 2FA provider, determine how well its features match your business’s needs. For example, if you need a 2FA validator API solution to safeguard payment processing, integrate a 2FA API developed with financial institutions in mind, such as Plivo. 
2. Assess scalability and future growth: Security gets more complex as your business expands. Choose an API 2FA solution that can adapt to these expanding security requirements. Go through their user reviews and case studies to learn more about how they’ve helped other businesses grow. 
3. Ensure compliance and data security: New research from IBM reveals the global average cost of a data breach in 2024 is $4.88 million. Look for a 2FA API provider with a long track record of meeting regulatory standards and safeguarding user data.

Key touchpoints for implementing 2FA in APIs  

When should you require your users to use 2FA? Well, it depends. 

Some companies require users to complete 2FA every time they log in. 

Others trigger 2FA during high-value transactions, such as when a user changes their password or wants to transfer funds. 

Remember, while security is important, don't forget about your user experience. It can be beyond frustrating to be locked out of your account because you can’t get your 2FA code. Finding the right balance of security and convenience is what makes that five-star customer experience. 

There are a few common scenarios when 2FA is a reasonable, expected part of the user experience. 

1. User login: Integrate 2FA into your user login page to add extra security. Choose the authentication methods such as SMS, voice, etc. based on your security needs and budget. 
2. Financial transactions: Integrate 2FA for financial transactions such as processing payments, transferring funds, or accessing financial statements. 
3. Account information updates: Implement 2FA for actions that alter account information, such as password changes, updating the email on file updates, or modifying a security setting. These changes can be signs of a potential account takeover from phishing or password reuse.
4. Access internal systems: Apply 2FA to access internal systems based on user roles. For instance, two-factor authentication (2FA) for the Plivo console lets users enable 2FA to protect their credentials and prevent unauthorized access.

How to integrate 2FA into your workflow 

Integrating 2FA into your existing system involves a few key steps. First, select a suitable 2FA method, such as SMS, email, or authenticator app. Next, implement a process to trigger the 2FA challenge after successful primary authentication. This could involve sending a code to the user's preferred channel.

Finally, incorporate a verification endpoint in your API to validate the entered 2FA code. It's essential to handle errors gracefully and provide clear feedback to users. Consider using a specialized 2FA API like Plivo to streamline the process and enhance security.

Step-by-step process for integrating 2FA into your workflow:

1. Determine API 2FA type:

Choose the type of 2FA you want to implement (e.g. email, authenticator apps, SMS, hardware tokens). Let’s say you want to send an SMS message that provides a user with an OTP. If you’re using Plivo’s API, a developer would use Plivo's API to make a request and send a 2FA message. 

a) Each API requires certain parameters; in this case, they include:some text

1.  An authentication ID and authentication token, the programmatic equivalent of a username and password. Plivo uses these to make sure the program is authorized to use Plivo services in general and the organization’s data in particular.
2. A source number — the phone number that should appear on the recipient’s handset to show where it was sent from.
3. A destination number — the phone number of the recipient.
4. Message text — the body of the message, which in the case of 2FA might say something like “Your security code is 123456. Enter this six-digit number on your login screen.”

2. Identify key touchpoints:

Determine which touchpoints require 2FA.

3. Choose an API 2FA provider:

Select a 2FA API provider that can help you secure accounts, prevent takeovers, and protect high-value transactions.

‍4. Integrate API 2FA:

Integrate the selected provider’s API in your existing authentication system by following its documentation. Plivo’s 2FA API, for example, offers advanced capabilities like sending images, sending to multiple recipients, and expiring messages that aren’t received within a specified time so you’re not charged for them.

You can also redact sensitive information such as part of the destination number and the message content if you have privacy constraints.

5. Perform unit testing:

‍Conduct automated tests that send OTP requests within specific time intervals to simulate and address potential vulnerabilities in all relevant scenarios such as: 

• Fund transfers: Test OTP requests during financial transactions to ensure secure processing
• Password resets: Verify OTP functionality during password reset requests
• Account updates: Assess OTP verification when updating sensitive account settings to maintain security.

Best practices to ensure comprehensive security:

• Use a pool of phone numbers from multiple carriers to support enterprise messaging demands and give routing options 
• Consider using QR codes that pair with authenticator apps
• Set up alerts for unusual login attempts or repeated login failures 
• Implement a secure process for account recovery through multiple channels 
• Ensure your 2FA implementation complies with regulatory laws such as HIPAA, GDPR, etc. depending on the location 
• Choose an API for 2FA that quickly identifies invalid phone numbers, and discovers the fastest delivery routes
• Divide your network into segments based on functions and apply strict access controls across all networks. 
• Subscribe to threat intelligence feeds and stay informed about emerging threats and vulnerabilities. 

By adhering to these best practices in implementing 2FA, you can enhance the security of both internal and external messaging systems.  

‍Note: For an in-depth understanding of 2FA and how it works, refer to our detailed guide.

Most business owners know passwords alone aren’t enough to keep your data safe. Between 2004 and July 2024, passwords were the most frequently leaked type of data, with two billion user passwords leaked during this period.

To better combat data breaches, more companies are turning to stronger authentication methods, such as multi-factor authentication (MFA), single sign-on (SSO), or two-factor authentication (2FA). 

What do all these acronyms mean, and how can you determine which solution is the right fit for your business? In this guide, we’ll break down each approach's core differences, benefits, and security considerations to demonstrate that combining MFA and SSO in a solution like Plivo’s Verify API is best for most businesses.

{{cta-style-1}}

What is single sign-on (SSO)?

Single sign-on (SSO) is a user authentication process that allows someone to log in once with a single set of login credentials and access multiple applications or services without needing to re-enter their username and password for each one. 

Think of SSO as a master key that opens many doors—users sign in once and get instant access to all their work tools without having to remember multiple passwords. This approach reduces login headaches and password fatigue, making it easier for users to stay secure and productive.

How does SSO work?

SSO verifies a user’s identity through a centralized system. When the user logs into an SSO portal, the system checks their login credentials. It then generates a token that grants access to various applications within the network, simplifying access management for authorized users. 

5 key benefits of SSO & why you should use it

Single sign-on offers several benefits, but here are five key reasons why you should consider using SSO:

• It streamlines the user experience: With SSO, users only need to use one password to log into a dashboard and access all connected applications—no more wasted time juggling multiple logins.
• It reduces password fatigue: Less is more. Fewer passwords mean less mental load, reducing the risk of weak or reused passwords and enhancing security.
• It improves productivity: Imagine the time saved when users can instantly access all the tools they need. This quick access means more focus on tasks and drives efficiency.
• It simplifies centralized management: IT teams can use SSO to manage user access from a single dashboard. It makes onboarding and offboarding new users smooth and hassle-free. 
• It lowers help desk costs: Fewer passwords mean fewer forgotten credentials. This leads to a significant drop in password reset requests, reducing the burden on IT support teams and cutting help desk costs.

3 key security risks of SSO you should consider

• It creates a single point of failure: If someone gains access to SSO credentials, they could access multiple services connected together, creating a significant security vulnerability.
• It relies on centralized authentication: If the SSO service experiences downtime or technical issues, users may lose access to all associated applications, causing operational disruptions.
• It becomes an attractive target for cyber attacks: Because SSO systems control access to multiple applications, attackers often target them. A successful breach could expose sensitive data across various systems.

What is multi-factor authentication (MFA)?

Multi-factor authentication (MFA) requires users to verify their identity using two or more forms, adding multiple layers of defense against unauthorized access. Think of it as a security system with multiple locks; even if someone knows your password, they still need other credentials to log in. 

How does MFA work?

A lot of people get confused between 2FA and MFA, but here’s the exact difference: 

2FA (two-factor authentication) always requires exactly two forms of verification, usually something you know (like a password) and something you have (like an OTP or security token). On the other hand, MFA covers two or more forms of verification, adding even more layers of security by incorporating things like biometrics (something you are) alongside what you know and have. 

Imagine overlapping circles in a Venn diagram—2FA is one circle inside the broader MFA circle, which lets you combine different layers for extra protection.

In implementation, it could look like this: after typing in your password, you might also need to enter a verification code sent to your phone or use a fingerprint scan. This layered approach makes it significantly harder for unauthorized users to gain access to user accounts.

3 key types of authentication factors used in MFA

Authentication factors are the methods used to confirm a user’s identity. In multi-factor authentication (MFA), at least two different factors are required to gain access. Here's a closer look at the types of authentication factors:

1. Knowledge factors (something you know):

These are login credentials that only the user knows, such as passwords, PINs, or answers to security questions. Knowledge factors are the most common type of authentication but are also considered the least secure due to the risk of being guessed or stolen through phishing attacks.

2. Possession factors (something you have):

These involve something the user physically possesses, like a smartphone, security token, or smart card. Possession factors are generally more secure than knowledge factors because they require an additional physical item that attackers would need to acquire. Common examples include SMS codes sent to a user’s mobile device or authentication apps like Google Authenticator.

3. Inherence factors (something you are):

These are biological traits unique to the user, such as fingerprints, facial recognition, voice recognition, or retina scans. Inherence factors provide a high level of security because they are unique to each individual and are difficult to replicate. This type of factor is commonly used in high-security environments, such as government agencies or financial institutions.

By using multiple authentication factors, MFA creates a layered defense, making it more challenging for attackers to gain unauthorized access.

5 benefits of MFA & why you should use it 

Here are five important benefits for businesses thinking about using MFA. 

• It enhances security. MFA adds multiple layers of security by requiring more than one form of verification, significantly reducing the risk of unauthorized access even if one credential is compromised.
• It protects against credential theft. Since MFA provides multiple authentication layers, even if a password is stolen, additional factors like a biometric scan or a verification code sent to a mobile device make it much harder for attackers to gain access.
• It helps comply with regulatory requirements. Many industries have regulations that require strong authentication methods. Implementing MFA helps businesses comply with PCI DSS, GDPR, and HIPAA standards.
• It reduces the risk of data breaches. By adding extra security layers, MFA helps prevent data breaches, which can save the business from costly fines and reputational damage.
• It improves user trust. Users feel more secure knowing that their accounts and data are protected by multiple layers of authentication, enhancing trust in the organization.

Security risks of MFA

• It can pose usability challenges. MFA can sometimes make the login process more cumbersome, potentially leading to user frustration or reduced productivity if not implemented carefully.
• It is vulnerable to phishing and social engineering attacks. Attackers might still use sophisticated phishing tactics to trick users into providing all required authentication factors, bypassing the additional security layers.
• It relies on secondary factors that can be compromised. If secondary authentication methods (like SMS-based codes) are compromised through SIM swapping or interception, attackers could still gain access despite MFA.

SSO vs MFA: the main differences

Here are five core differences between MFA and SSO:

1. Different goals: MFA enhances security by requiring multiple authentication factors to verify a user's identity. SSO focuses on convenience by allowing access to multiple applications with a single set of credentials; instead of remembering multiple usernames, users can easily sign in once and access all authorized applications they need. 
2. Security vs. convenience: MFA offers stronger protection by requiring multiple authentication methods. SSO, on the other hand, focuses on user convenience, which can lead to vulnerabilities if credentials are compromised.
3. User experience: SSO simplifies the login process and reduces password fatigue. Meanwhile, MFA adds extra steps, which can feel like a hassle to some users but adds extra layers of security.
4. Setup complexity: Setting up MFA involves integrating various authentication methods, which can be complex. SSO requires connecting different applications to one central login, which simplifies user access but can be tricky if not done right.
5. Risk management: MFA minimizes the risk of unauthorized access with extra verification layers, while SSO simplifies access control but can become a single point of failure if hacked.

Both SSO and MFA have their place in your security scheme, depending on what’s more important for your business—security or convenience.

SSO vs. 2FA vs. MFA

When securing access to your systems, understanding the differences between SSO, 2FA, and MFA is crucial. Each method can impact your organization’s security, budget, and user experience. Let’s dive into how these authentication methods compare across key factors.

Cost implications

Implementing MFA or 2FA might involve additional costs due to the need for specialized software or hardware (like biometric scanners or security tokens). SSO solutions can reduce password and user support costs but may require investment in a robust identity management system.

Impact on user experience

SSO enhances user experience by reducing the required logins, while MFA and 2FA may introduce additional steps but offer stronger security. The choice depends on balancing convenience against security measures.

Implications for businesses

Businesses need to consider the nature of their operations, regulatory requirements, and user base when deciding on an authentication method. While MFA offers the highest security, SSO can greatly improve productivity and user satisfaction.

4 important things for selecting the right provider for your organization

If you’re looking for an authentication solution for your business, here are the key things you should consider: 

1. Security needs and compliance requirements

To begin with, consider the sensitivity of the data your organization handles and any regulatory requirements, like GDPR, HIPAA, or PCI DSS, that might mandate specific authentication methods. For high-security environments, a combination of SSO with MFA can provide a balanced approach. 

With Plivo, you get built-in compliance features that help you adhere to regulations without adding extra costs. Plivo's Fraud Shield, for example, protects against SMS pumping fraud, ensuring your authentication processes remain secure and compliant.

66% of customers prefer to use text messages to engage with companies. Since text is more accessible, 37.5% of customers actually wish for brands to use text message marketing. 

But here’s the challenge: with up to 98% open rate for text messages—the invincibility of SMS marketing invincibility undoubtedly draws a huge number of marketers to the fray. As a result, customers are bombarded with SMS from e-commerce brands all over the world. 

This means you have to compete for every click and conversion. To stand out from the crowd, you need to use best practices for SMS marketing. 

In this blog post, we’ve compiled a list of some tried-and-tested best practices for SMS marketing to help you kickstart your next SMS marketing campaign. 

Wait, let’s take care of the law first!

CAN-SPAM Act

Enforced by the Federal Trade Commission (FTC), the CAN-SPAM Act covers certain types of SMS marketing. This law sets rules for commercial messages and gives people the right to opt out if they don’t want to hear from you anymore. 

You definitely wouldn’t want to ignore it as the outcome can cost you big time—hefty fines, which can reach up to $51,744 per individual violation. Also, companies may risk being blacklisted by telecom providers if they consistently send unwanted messages.

What you need to do:

• Make sure your messages aren’t misleading
• Clearly identify yourself as the sender
• Always include a way for people to opt-out
• Respect opt-out requests immediately

GDPR (General Data Protection Regulation)

GDPR is important if you’re doing business in the EU or have customers there. This law regulates how you can collect, store, and use personal data—including for SMS marketing.

What you need to do:

• Ensure that customers actively opt-in to receive SMS communications by requiring them to check a box or click a button
• Collect distinct consent for each communication channel (e.g., SMS, email, push notifications).
• Be transparent about how you’ll use their data
• Keep data secure and only use it for the purposes they agreed to
  

TCPA (Telephone Consumer Protection Act)

As per the TCPA, you need to have their express written consent before sending out any marketing messages. 

What you need to do:

• Get clear consent before sending marketing texts
• Send marketing messages only during reasonable hours, generally between 8 AM and 9 PM in the recipient's local time zone
• Keep a record of the consent provided by each customer

Best practices for SMS marketing 

First, introduce yourself!

Imagine receiving a text from a random number with a great offer, but you have no idea who it's from. The first instinct might be to ignore it or, worse, report it. That’s the last thing you want for your brand. 

Therefore, you should introduce yourself in each message to ensure your audience knows exactly who’s reaching out and why they should pay attention.

A simple introduction helps establish credibility and prevents your messages from being mistaken for spam. These are quite handy, especially for two-way messages, as customers hardly reply to unknown numbers. 

See how Dr. Squatch introduces the brand before beginning the message content. 

Seek permission before sending messages

Before you start sending SMS messages, it is crucial to seek permission from the recipient. As mentioned above, the opt-in process is legally required in many regions.

As noted above, regulations like the TCPA are set up in the U.S. to protect consumers from unwanted communication. If you fail to comply with these regulations, you may face fines or penalties.

By having customers opt-in, you confirm that they are interested in hearing from you. It also increases the chances of customers reading your messages and responding to your offers.

💡Pro Tip: Always send a confirmation message whenever someone opts in. This not only reassures them that they’re successfully subscribed, but it also provides an opportunity to thank them and perhaps offer an immediate incentive, like a discount code, to start the relationship on a positive note.

For example, after someone opts in, you could send a message like: "Thank you for subscribing to [Your Brand Name] updates! Enjoy 10% off your next purchase with the code WELCOME10."

Provide opt-out options

In any SMS marketing strategy, you must give recipients an easy way to opt-out. Like opt-in, the TCPA in the U.S. requires that all marketing messages include a clear and simple way for recipients to opt-out. Failing to provide this can result in significant legal penalties.

Also, providing an opt-out option shows that you respect your customers' choices.

At the end of each SMS, include simple, clear instructions on opt-out. A common practice is to add a line like "Reply STOP to unsubscribe."

Don’t send messages too often

96% of customers say that they are occasionally annoyed by brand messages. The number one reason for this annoyance was “messaging too frequently”. 

​​While there’s no one-size-fits-all rule, you can limit your promotional messages to 2-4 monthly messages. This allows you to stay on your customers' radar without overwhelming them. 

This number can vary depending on your industry, your specific audience, and the messages you send. For instance, a daily deal alert might justify more frequent messaging, but less is often more for general updates or promotions.

Time your texts well

To maximize customer engagement, it’s important to send your messages during the hours when your customers are most likely to be receptive. 

Generally, the best times are between 9 AM and 8 PM local time. Sending messages too early in the morning or late at night can come across as intrusive, which can annoy your customers.

To accelerate your campaigns, you can try an all-in-one SMS marketing platform like Plivo CX to automate your messages. It is an AI-powered customer engagement platform that ensures your messages reach the right customer segment at the right time. 

Plus, you can schedule messages whenever you see fit. It also lets you select your preferred channels, set timings, and schedule the campaign. On top of it, with Copywriter AI, you can create highly personalized and nuanced text messages

Most importantly, Plivo CX leverages Plivo’s low-latency premium carrier network, which is spread across 190+ countries. As a result, you can cut down SMS marketing costs by up to 70% while sending timely messages, even if your customers are spread across different regions.

Use simple language 

SMS has a better open rate than email because it is short and simple. Your message should be easy to read and understand at a glance. Complicated words or industry jargon can confuse your audience and reduce the effectiveness of your message.

Here, you can also use Copywriter AI to maintain simple and consistent brand language across all messages. All you have to do is provide Copywriter AI with your objective and determine the goals, parameters, and urgency for your SMS.

After completing this step, you'll get several versions of your message to pick from. You can review and refine these versions before sending the most suitable one.

Avoid extensive informal wording

You may go overboard with slang while trying to appeal to a younger audience–especially with Gen Z. 

However, excessive slang and tonal dilution can obscure your message and come off as inauthentic. Even with younger customers, you should never sacrifice quality for trendiness. 

Instead, aim for a conversational yet professional tone, ensuring your message is universally understood.

Share relevant, valuable content 

It is crucial to send content relevant to your audience's interests and add value to their experience. Here are some examples of the types of content that work well for different e-commerce brands:

Segment customers for personalized messages 

34% of customers get annoyed by messages irrelevant to their needs or interests. Generic messages won’t cut it anymore. Customers want a personalized experience. 

You can personalize your messages by segmenting your audience based on purchase history, browsing behavior, demographics, or geographic location. Then, tailor your messages to be more relevant and appealing to each group.

You can try Plivo CX’s Audiences to automate the segmentation process. It syncs contacts from your Shopify store in real time and allows you to segment customers based on unlimited rules.

Audiences provide 360° visibility into your customers, so you can see repeat purchases, holiday shoppers, non-active customers, new leads, etc. This information lets you send highly personalized messages to each group. 

Also, the segment builder is code-free, so anybody on your team can create customer segments.

Add links as CTA

Including links in your SMS messages is a powerful way to drive immediate action from your customers. 

Links allow customers to access the content or offer you’re promoting instantly, making it easier for them to take action. By adding links as CTAs, you can also track clicks and measure the effectiveness of your campaign in real time.

Ensure your message indicates what the customer should do next, such as "Shop Now," "Learn More," or "Get Offer.” Use URL shorteners to keep your messages clean and concise. This also helps you stay within the SMS character limit.

Add MMS and emojis

Incorporating Multimedia Messaging Services (MMS) such as images, videos, or GIFs, and emojis into your SMS marketing can make your messages more engaging and visually appealing. These elements can help your brand stand out in a crowded inbox and convey your message more effectively.

For e-commerce brands, MMS is a terrific way to visually display new arrivals, special offers, or product details.

On the other hand, emojis can add a touch of personality and emotion to your messages, making them feel more relatable and fun. However, it’s important to use them strategically and not overdo it.

Giveaways are a terrific way to create a buzz around your brand and reach a wider audience. But running giveaways (especially on a big scale isn't easy). To be specific, you need exceptional technical support to increase reach, manage data, and measure return on investment. 

Having an omnichannel marketing platform can help you run giveaways on the scale. In this post, we will look at 8 popular ideas for a giveaway and how to execute them well. 

1. Free product with purchase

Giving a free product with every purchase is one of the popular marketing giveaway ideas to promote a new product or any underselling product. You can create a small bundle of the new product with your existing ones or offer a free sample for a minimum purchase amount.

Example of free product with purchase giveaway

Ashley & Co, a luxury brand, offered free samples of their products for all purchases above $50. This move was to make customers familiar with all ranges in product lines.

Tips to run effective free products with purchase giveaways

Choose the best-selling products

Give complementary products with your existing best-selling products for maximum reach. These are the products for which you have already established trust, and anything coming with it will look credible.

Select the product bundles wisely

Create product bundles that complement each other and intrigue customers. For instance, a user purchasing hair shampoo may be interested in getting a complimentary conditioner or serum.

Set a minimum order condition

To avoid heavy losses in such giveaways, you can set a minimum order condition. Let's take the example discussed above. If you are offering free conditioner, you can offer it for all orders above a certain amount or only shampoo bottles above a certain size. 

This way, you are making enough profit from the order to offer anything complimentary.

Promote the offer

Promote the offer across all your marketing channels, clearly highlighting the free item.

Set a limit of one free product per customer

These promotions are mostly for free trials, so set a limit so that a customer can avail of the offer only one time. This step ensures you are not running out of inventory and reaching more customers. 

2. Buy one get one free (BOGO)

Buy one get one free (BOGO) or Buy two get one free offers are great campaign giveaway ideas for eCommerce businesses to boost sales. It is also an excellent strategy to clear out the inventory and attract more customers.

This strategy works particularly well with fast-moving products that customers use regularly, such as clothing, accessories, and more. For high-priced items, you can also run "Buy three get one free" campaigns. 

Example of buy two get one free giveaway

P&Co, a clothing and lifestyle brand, ran offers on its T-shirts. Customers could buy two and get one free. 

Tips to run effective BOGO giveaways

Choose high-demand products

Choose the products that customers need in bulk and would like to make the best of BOGO giveaways.

Create a sense of urgency

Run limited-time offers and send alerts if inventory is running low to boost purchases.

3. Brand partnership bundle

Brand partnership giveaways are strategies where two brands come together to create a product bundle. This approach helps both brands to tap into each other's audience and gain more visibility. 

Example of brand partnership giveaway

Crate and Kids (a baby products brand) and Monte Design (a future brand) partnered together to run a giveaway. They promoted a nursery chair, which was relevant to both brands' audiences. 

Tips to run effective brand partnership giveaway

Identify the right brand to partner with

Partner with a brand that has a shared target audience and the products complement each other. For instance, a vegan food brand complements a fitness product brand well.

Set a goal first and design the campaign backward

Identify what you want to achieve with the giveaway and then work backward. For instance, if the goal is to get trials done for a new product, then design a product bundled with that product. 

If the goal is to reach a wider audience, you can run a collaboration and give the product to one of the lucky winners.

Cross-promote the products

The main goal of brand partnerships is to reach each other's audience. You can plan giveaway promotions on all marketing channels of both brands. 

4. Seasonal and holiday-themed giveaways

Seasonal and holiday-themed giveaways are campaigns where businesses offer free products for specific seasons or holidays. Customers keep the spending budget to shop around the holidays, making it a great time to run a promotion. 

Example of seasonal and holiday-themed giveaways

NOBULL, a footwear brand, ran a giveaway on Black Friday, and the lucky winner would get a pair of shoes. 

Tips to run effective seasonal and holiday-themed giveaways

Choose products that align with the holiday

Offer products that customers need the most on holiday. You can check your past order history around similar times last year to identify a pattern and also tap into online conversations to find what's trending. 

Keep the messaging festive

It's not a regular promotion but a festival promotion. Keep the messaging festive to create an emotional connection with customers and live up to the holiday spirit.

Start planning in advance

Plan the campaign in advance to get more time to run promotions and execute it strategically. 

Keep something for last-minute shoppers

Some customers are also looking for products at the last minute, and you can plan flash offers to capitalize on this rush. 

5. Tag-a-friend giveaways

Tag-a-friend is another common giveaway where brands ask participants to tag their social media connections in the posts, and randomly chosen participants get the prize. 

This is a great idea for generating brand buzz as it's simple to execute for brands and easy for customers to participate in. 

Example of tag-a-friend giveaway

Tips to run effective tag-a-friend giveaways

Keep the rules simple

Make it easy for users to participate in the giveaway by keeping the rules as simple as possible and adding detailed descriptions.

Create a sense of urgency

Run limited-time giveaways to encourage quick customer participation.

Collaborate with influencers for promotion

Collaborate with influencers to promote the giveaway for maximum reach.

6. Product bundle giveaway

A product bundle giveaway is another promotional strategy where you can create a small collection of relevant products and give any product for free. It helps in two ways. 

First, it increases the average order value as customers buy bigger bundles to get the free item. Secondly, it also helps in the promotion of the items you are giving for free. 

Example of product bundle giveaway

Tips to run effective product bundle giveaways

Choose a theme for the product bundle

Take related products that are exciting together as a bundle for the customer.

Allow flexible product bundling

Give customers the option to add or remove products from the bundle as per their choice so they don't drop the bundle for 1-2 products that don't match their interests.

7. Gamified giveaways 

Gamified giveaways are different from regular giveaways. It engages customers by using game-like elements. 

For example, customers are required to enter the giveaway by participating in a quiz or a mystery box challenge and more. It is one of the cool giveaway ideas for engaging with customers. 

Example of gamified giveaways

Tips to run effective gamified giveaways

Use common game mechanics

Keep the giveaway rules simple, like spin to win, mystery box, etc, which customers are familiar with. It reduces friction and boosts participation.

Make it shareworthy

Make the rules of the game interesting and encourage participants to share them on social media to gain more visibility. 

8. Influencer giveaway

An influencer giveaway is one of the campaign giveaway ideas where you can collaborate with influencers to promote giveaways. Influencers' followers participate in the giveaway based on certain rules. You can discuss the rules with the influencer in advance. 

The best part of this type of giveaway is that influencers have massive reach, so you don't need another big promotional strategy to make the giveaway a hit. 

Example of influencer giveaways

Tips to run effective influencer giveaways

Choose influencers in your target audience

Choose influencers whose followers lie more in the demographics you are targeting. Also, check if the influencers' usual social media messaging aligns with your brand persona.

Keep the giveaway rules simple

Make it simple for participants to take part in giveaways for maximum reach. 

Create interesting content around giveaways

The good part about collaborating with influencers is they can create interesting content around your products, which will make both your products and giveaway enticing.

In almost 31% of breaches in the past decade, and 60% in just the past year, exposed credentials have played a role. Despite the effort of many organizations to enforce strict password policies—such as the monthly rotation of 24-character passwords—huge breaches continue happening. 

Cyber attacks use credential stuffing, brute force, or abuse by enumeration to exploit weak security points. But there also remains the element of human error. The average person now has 100 passwords, up 25% from 2020. As a result, users typically fall back on poor password practices to make life easier. 

Instead of setting up users to fail, companies can help boost account security using one-time passwords. A one-time password (OTP) is one of the more mature options within static-passwordless methods. 

In this blog post, we’ll dive into what OTPs are, their benefits, how they work, what to know about PAM, and how to implement them in your business. 

{{cta-style-1}}

What are one-time passwords (OTPs)?

An OTP is a randomly generated, one-time validity code used for a single login session or transaction. Unlike static passwords, which remain the same until the user changes them, OTPs are valid for a very short period or just one use. This makes them a very useful tool in the fight against unauthorized access.

OTPs add an extra layer of protection over transactions and logins for online banking. E-commerce websites, at their end, deploy OTPs during checkout to prevent fraud. Service businesses, on their part, depend on OTPs to guarantee the security of their critical systems. 

One-time passcodes also play a big part in two-factor authentication and password recovery. They ensure that only the rightful owner can access an account or reset a password. Ultimately, OTPs are a critical element in mitigating the risk of a cyber-attack or data breach. 

5 benefits of using one-time passwords

There are plenty of benefits to using OTPs, but here are some key ones.

1. They enhance security through unique, temporary codes

OTPs align with the zero trust mindset, which assumes there’s no effective defensible perimeter that may protect a customer or an organization. OTPs work on a “never trust, always verify” principle by generating unique, temporary codes for users. Even if someone intercepts the OTP, its short lifespan renders it useless in minutes. 

Moreover, when you use solutions like Plivo that offer built-in security measures like Fraud Shield, you gain an added layer of protection. Fraud Shield is specifically designed to mitigate fraud risks such as SMS pumping and account token takeovers. 

This ensures your messaging infrastructure remains secure and resilient against fraudulent activities.

2. They protect against password reuse and interception

Reusing passwords across multiple sites is a common but risky practice. OTPs mitigate this risk by using a unique password each time. Additionally, because OTPs are often sent through secure channels like SMS or an authenticator app, they’re less susceptible to interception compared to static passwords.

Plivo offers advanced features that enhance your OTP delivery and performance.

Plivo supports real-time delivery report notifications so you can track how your messages are performing globally. This provides valuable insight into your delivery rates and helps you gauge the effectiveness of your OTP strategy.

Moreover, Plivo offers pre-approved templates optimized for conversions. These ready-made message templates are not only pre-approved for compliance with industry regulations but are also crafted to maximize engagement and drive conversions.

By using these templates, you save time and effort in creating messages from scratch, allowing you to focus on what really matters—connecting with your audience.

3. They’re simple to use 

Customers need not only robust protection but also a seamless experience. OTPs are a simple way to make logging in more secure. 

On the client side, implementing OTP solutions has never been easier with Plivo. Plivo offers a clear and straightforward API that simplifies OTP setup. Using standard HTTP verbs and status codes, Plivo ensures easy integration with your systems.

Whether you’re using Python, Ruby, Node, PHP, Java, .NET, Go, or even cURL, Plivo keeps the setup process consistent and streamlined. All API requests are secured over HTTPS, keeping your data safe during transmission.

Plivo’s API also authenticates requests with your Auth ID and Auth Token, ensuring secure OTP transactions. It supports JSON input in all POST requests, making data handling simple, and for larger deployments, features like timeouts and proxy settings are easy to configure within the server SDKs.

4. They offer versatility across platforms

OTPs are incredibly adaptable and can be used for different business purposes, such as logging into a bank account, verifying an online purchase, or accessing sensitive work systems. This flexibility makes OTPs an essential tool in many scenarios: no matter the context, your users can authenticate securely.

With Plivo, this versatility is enhanced by a global reach. Plivo’s infrastructure is designed to ensure high deliverability rates and minimal latency across 220 countries and territories, making it a reliable choice for businesses that operate globally. 

5. They help meet compliance and regulatory standards

For industries such as finance, healthcare, and media, adhering to strict regulatory standards is not just a requirement—it’s a necessity. OTPs play a critical role in helping businesses meet these rigorous data protection standards by providing a secure and compliant authentication method.

Plivo’s OTP solutions are designed with compliance in mind, supporting standards like GDPR and HIPAA. With built-in security features and detailed reporting, Plivo makes it easier for businesses to demonstrate compliance and protect sensitive user data. 

By using Plivo, you ensure that your authentication processes are secure and aligned with the latest regulatory requirements, giving you and your customers peace of mind.

How do one-time passwords work?

OTPs operate on a straightforward yet highly secure principle: generating a unique, time-sensitive code for each authentication attempt. 

The process typically begins with an algorithm that factors in variables such as time or a shared secret key between the server and the user’s device. This ensures that each OTP is unique and can be validated only within a specific timeframe.

For instance, a time-based one-time password (TOTP) uses the current time as one of its inputs, generating a new OTP every 3-5 minutes. When a user requests access, the server generates the OTP using the same algorithm and parameters. 

The user enters the OTP they receive, and the server checks it against the one it generated. If the two match within the allowable time window, access is granted. This method ensures that even if an OTP is intercepted, it becomes invalid almost immediately, thus significantly enhancing security.

Consider a scenario where an employee logs into a corporate system. After entering their username and password, the system prompts them to enter an OTP. The employee’s mobile authenticator app generates an OTP based on the current time and a shared secret key. 

The employee then inputs this OTP, and the server validates it against its own calculation. This dual-factor authentication allows only the legitimate user to gain access, providing a robust layer of security against unauthorized access.

OTPs & privileged access management (PAM): what to know

Privileged access management (PAM) is a cornerstone of enterprise security, safeguarding the most sensitive accounts and systems underpinning an organization’s critical operations. 

OTPs integrate seamlessly with PAM solutions, providing a dynamic layer of security that complements existing controls. When a user attempts to access a privileged account, the PAM system can trigger an OTP request, requiring the user to provide a time-sensitive code in addition to their regular credentials. 

This integration ensures that even if attackers compromise the primary credentials, they would still be blocked from accessing the system without the corresponding OTP. The result is a more resilient defense against unauthorized access to critical enterprise systems.

One-time passwords versus dynamic secrets

Dynamic secrets are temporary, on-demand credentials that are automatically generated and revoked by a system or service, providing enhanced security and access control.

While both OTPs and dynamic secrets provide a means for strong authentication, they serve different purposes and offer distinct advantages. 

Differences between OTPs and dynamic secrets

• Purpose:some text
  • OTPs: Primarily used for user authentication as a temporary, one-time code for access.
  • Dynamic Secrets: Commonly used in API security to facilitate secure communication between systems or applications through short-lived authentication tokens.
• Use Case:some text
  • OTPs: Ideal for scenarios where a user needs to authenticate themselves for a single session or transaction.
  • Dynamic Secrets: Better suited for environments requiring continuous, automated authentication between systems.

Benefits of OTPs vs. Dynamic Secrets

• OTPs:some text
  • Simple and effective for end-user authentication
  • Easy to implement and user-friendly
  • Provides a high level of security with minimal friction for the user
  • Offers a straightforward solution that ensures secure access without compromising the user experience
  • OTPs can be cost-effective in terms of implementation and maintenance, as they are often simple to generate and require less infrastructure,
• Dynamic Secrets:some text
  • More complex and suited for scenarios requiring ongoing, automated authentication
  • Ideal for securing continuous communication between systems or applications
  • Dynamic secrets may have higher upfront costs due to the need for specialized systems to generate and revoke credentials in real time

5 best practices for implementing one-time password solutions 

When adding one-time passwords (OTPs) to your security setup, keep these five best practices in mind. 

1. Prioritize strong algorithm selection: Choose a robust algorithm to generate your OTPs. Look for industry-standard options like HMAC-based one-time passwords (HOTP) or time-based one-time passwords (TOTP). These algorithms ensure that your OTPs are secure and reliable.‍
2. Set appropriate expiry times: Your OTP solution should have a balance between security and usability. Implement short expiry times—typically 3-5 mins—for each OTP. This minimizes the window of opportunity for unauthorized use while still allowing users enough time to complete the authentication process.
3. Offer multiple delivery channels: Flexibility is key when it comes to OTP delivery. Whether through SMS, email, or voice, multiple delivery options ensure that users can access their OTPs in the most convenient way. This approach enhances the user experience and provides a backup in case one channel fails.‍
4. Implement comprehensive monitoring and logging: A successful OTP implementation doesn’t stop at setup. It’s crucial to monitor and log OTP generation and validation activities. This data provides valuable insights into authentication patterns and helps identify potential security threats.‍
5. Educate users on security best practices: Lastly, but equally important, is user education. Make sure your users understand the importance of keeping their OTPs secure. Provide clear guidance on not sharing OTPs and recognizing phishing attempts. A well-informed user base is a critical component of any successful security strategy.

By following these best practices, you can ensure that your OTP implementation is both secure and user-friendly, providing customers with strong protection without compromising on ease of use.
