# Prerequisites

> Requirements for setting up Plivo SMS with Auth0 MFA

To start using Plivo with Auth0, you’ll need

1. Make sure you have an [Auth0 account](https://auth0.com/signup) and **tenant**.

2. Your **Plivo Auth ID and Auth Token**: You can find your Plivo Auth ID and Auth Token on the overview page of the [Plivo console](https://cx.plivo.com/home).

3. **A Plivo number** *(optional)*: You must have an SMS-enabled Plivo phone number to send SMS messages to numbers in the US and Canada. Purchase numbers from the [Phone Numbers](https://cx.plivo.com/phone-numbers) page of the Plivo console, or by using the [PhoneNumber API](/docs/numbers).

Plivo provides an SMS messaging service that Auth0 can use to deliver multi-factor verification via SMS messages. The following steps will enable you to add SMS-based MFA via the Plivo SMS API to the login flow for the tenant in which you’re working.

<Note>
  The following steps will add text-message-based MFA to the login flow for the tenant in which you're working. We highly recommend testing this setup on a [staging or development server](https://auth0.com/docs/dev-lifecycle/set-up-multiple-environments) before making the changes to your production login flow.
