Two-Factor Authentication (2FA)

Two-Factor Authentication (2FA) is a security method where the user uses two different authentication methods to verify their identity.

Traditionally, the first layer is a username and password. The following layer is then either a code, PIN, or unique identification that only the user trying to log in possesses. For example, the following layer could ask for the user’s fingerprint, face for facial recognition, or a code sent to their personal email or phone number.
