What does MFA stand for in cybersecurity?

• A. Multiple Frequency Authentication
• B. Multi-Factor Authentication
• C. Mandatory Free Access
• D. Mainframe Access

Answer: (B)

In cybersecurity, this concept is about strengthening login security by requiring more than one form of verification. Multi-Factor Authentication means you must provide two or more factors to prove your identity, such as something you know (a password), something you have (a code from an authenticator app or a hardware key), or something you are (a fingerprint or facial scan). This layering makes it harder for someone to gain access if one factor is compromised. The correct term here is Multi-Factor Authentication. The other phrases don’t fit because they describe unrelated ideas: Multiple Frequency Authentication isn’t a standard security term, Mandatory Free Access suggests unrestricted entry, and Mainframe Access refers to accessing a specific type of computer system rather than a method of verifying identity.
