MFA
acronymsecurityprivacy
Stands for: Multi-Factor Authentication
Requiring two or more independent proofs of identity to log in, not just a password.
Multi-Factor Authentication combines something you know (a password) with something you have (a phone or key) or are (a fingerprint), so a stolen password alone is not enough. It is one of the single most effective defences against account takeover.
Also known as: mfa, 2fa, two-factor, multi-factor authentication, totp
