MFA / 2FA
Two-factor authentication: on top of the password, a second proof (code, app, key) to prove it really is you.
MFA (or 2FA) requires at least two different proofs of identity to log in, for example a password plus a code on your phone. That way, a stolen password is no longer enough to get into your account. Not all methods are equal: an authenticator app or a physical key protects better than a code by text message.
