What does MFA stand for in security terms?

• A. Multi-Factor Authentication
• B. Multi-Fire Authorization
• C. Multi-Form Authentication
• D. Managed File Access

Answer: (A)

Multi-Factor Authentication means requiring more than one method to verify a user’s identity. In security, MFA combines factors from different categories—something you know (a password), something you have (a hardware token or authenticator app), and/or something you are (biometrics). This layered approach makes it much harder for attackers to gain access, because even if one factor is compromised, additional factors still protect the account. The standard term for this concept is Multi-Factor Authentication. The other phrases aren’t recognized security terms and would not convey the same meaning: one suggests an unrelated concept, another could be mistaken for multiple methods, and the last refers to file access control rather than identity verification.
