What is multi-factor authentication?

Two-factor authentication is an authentication method that requires multiple verification methods, providing an additional important layer of security for user logins and transactions. It works by requiring two or more of the following authentication methods:

Something the user knows (usually a password)
Something the user has (a trusted device that cannot be easily replicated, such as a phone)
own characteristics (biometric identification system)

Azure Multi-Factor Authentication (MFA) is Microsoft's two-factor authentication solution. Azure MFA helps protect access to data and applications while meeting user needs for a simple sign-in process. It provides strong authentication through a range of verification methods, including phone calls, text messages, or mobile app verification.
