What is MFA and why is it important?

• A. Multi-factor authentication; it adds verification beyond passwords reducing risk
• B. Multi-Functional Access
• C. Mandatory Fast Access
• D. Micro-Factor Authorization

Answer: (A)

Multi-factor authentication is a security measure that requires more than one form of verification to prove who you are. It goes beyond a single password by asking for at least two factors: something you know (like a password), something you have (such as a code from a phone or hardware token), or something you are (biometric data). This layered approach makes it much harder for attackers to gain access, because even if one factor is stolen or guessed, an additional factor is still needed. That’s why MFA is important: it reduces the chances of account compromise from stolen credentials, phishing, or password reuse, and it’s a standard best practice for protecting systems and sensitive information. The other choices don’t describe MFA: they either rename the concept, imply faster access, or use nonstandard terminology.
