Multi-factor authentication (MFA), sometimes called two-factor authentication (2FA), is a security enhancement that requires you to present two pieces of evidence when logging in to an account. Your credentials must come from two different categories to enhance security.
Credentials can fall into any of these three categories:
Knowledge factors: Something you know; like a password, PIN, or security questions
Ownership factors: Something you have; like a mobile device (text message), email account, or a USB security key (e.g., YubiKey)
Inherence factors: Something you are; biometrics; like your fingerprint, iris pattern, or facial features
