Explanation
Multifactor authentication (MFA) requires at least two distinct authentication factors from different categories to verify a user's identity. The combination of a fingerprint and a password meets this requirement by utilizing a biometric and a knowledge factor.
Common mistakes.
- A. This combination only utilizes factors from the 'something you know' category (PIN and employee ID), failing to incorporate at least two different factor types required for true multifactor authentication.
- C. Both a smart card and a hardware token fall under the 'something you have' authentication factor, thus not providing two distinct types of factors for multifactor authentication.
- D. Both voice recognition and retina scan are biometric factors, falling under the 'something you are' category, which means this combination does not provide distinct authentication factor types.
