What is a key benefit of multi-factor authentication in TA operations?

• A. Strengthens verification beyond passwords, reducing social engineering risk.
• B. Makes login slower with no security benefits.
• C. Is unnecessary if you have strong policies.
• D. Increases user friction with no security gains.

Answer: (A)

Multi-factor authentication adds a second verification step beyond a password, such as a code from an authenticator app or a hardware token. This means someone who knows a password—even if obtained through social engineering—still needs the second factor to gain access. In TA operations, where access to sensitive tools and data must be tightly protected, MFA provides a reliable layer of defense by tying access to something you have or something you are in addition to something you know.

This is why it’s the best choice: it strengthens verification beyond passwords and directly reduces risk from social engineering and credential theft. The other statements treat MFA as irrelevant or harmful to usability, which isn’t accurate—the security benefits outweigh the minor friction, and strong policies alone can’t defend against compromised credentials.
