Multi-factor Authentication

Multi-factor authentication involves providing more than just a username/password to prove your identity.

It usually involves providing two of the following:

• Something you know - a username/password combination, a PIN, etc.

• Something you have - pressing a notification that appears on your phone, a badge that is scanned, etc.

• Something you are - biometrics such as a face scan, palm scan, fingerprint scan, retina scan, etc.

Requiring multiple factors of authentication greatly increases the security. Even if an attacker learns the target's password, they won't be able to login to the target's account.
