Two-Factor Authentication

What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is a secure method of verification that requires the end user to type an unique temporary PIN code they receive via their mobile phone into the application they're trying to access. The PIN can be received via SMS or an automated Voice call. This method of combining a known password to a physical device (i.e., a mobile phone) can greatly improve security and identity verification.
