Two-Factor Authentication (2FA)

A specific form of multi-factor authentication that requires exactly two independent verification factors, most commonly a password plus a one-time code from an app, SMS, or hardware token. It is one of the most widely deployed forms of MFA, though SMS-based 2FA is considered weaker than app-based or hardware-based methods due to SIM-swapping risk.
