MFA stands for what in cybersecurity?

• A. Master File Access
• B. Multi-File Arrangement
• C. Magnetic Field Analysis
• D. Multi-Factor Authentication

Answer: (D)

Using multiple verification factors to authenticate means you prove who you are with more than one form of evidence. Multi-Factor Authentication requires at least two independent factors, such as something you know (a password), something you have (a code from a phone or hardware token), or something you are (a biometric like a fingerprint). Requiring more than one factor makes it much harder for someone to gain access if they only know one piece of information, like a password, because they’d still need the second factor. That’s why this option is the correct one. The other terms listed aren’t standard cybersecurity concepts for proving identity: they don’t describe the authentication process used to secure logins. MFA is widely deployed to reduce credential-based breaches, though it isn’t foolproof and can introduce user friction or other risks if not implemented carefully.
