Two-Factor Authentication
Two-factor authentication (2FA) is a security method that requires two different ways to prove a user’s identity. In other words, a user needs more than just a password to access their account. In addition to entering their password, they also have to provide another piece of information that is only known to them.

So if a bad actor were to steal a user’s password, they still wouldn’t be able to log in unless they had access to something else, like an authenticator app or device, that only a user possesses.

Common types of 2FA include:

Hardware tokens for 2FA
SMS text-message 2FA
Software Tokens for 2FA
Voice-based 2FA
