MFA
Multifactor Authentication
An access control requiring more than one proof of identity, such as a password plus an authenticator prompt, passkey, certificate, or hardware token.
MFA matters because identity, access, endpoint, and data controls shape how Microsoft environments are protected. Readers should understand the term and then be able to move into security assessment, conformity, or remediation guidance.
