In eAuthentication, MFA enhances security by using multiple forms of what?

• A. Password policies.
• B. eAuth mechanisms.
• C. Biometric templates.
• D. Security tokens.

Answer: (B)

Multifactor authentication strengthens eAuthentication by requiring more than one method to verify who you are. It doesn’t rely on a single factor; instead, it combines different eAuth mechanisms so you prove your identity in multiple ways, such as something you know, something you have, or something you are. That combination is what MFA is about, making it harder for an attacker to gain access with just one compromised factor. The other options point to individual elements (a single biometric form, a single token) or to policy, which don’t capture the idea of using several verification methods together.
