What is ‘Two Factor Authentication’ or 2-step verification?

Two-factor authentication (2FA), sometimes referred to as two-step verification, is a security process in which users provide two different authentication factors to verify themselves.

2FA provides a higher level of security than authentication methods that depend on single-factor authentication (SFA), in which the user provides only one factor — typically, a password or passcode. Two-factor authentication methods rely on a user providing a password, as well as a second factor, usually either a security token or a biometric factor, such as a fingerprint or facial scan.
