Multifactor authentication (MFA) enhances security by requiring a user to present at least two distinct verification factors from different categories (e.g., something you know, something you have, something you are).
Common mistakes.
- A. This describes the purpose of digital certificates or public key infrastructure (PKI), not multifactor authentication directly.
- B. While biometrics (biological characteristics) can be one factor in MFA (something you are), MFA itself requires at least two different categories, not just one type of factor.
- D. An application programming interface (API) is a set of rules for software interaction and has no direct relation to the concept of multifactor authentication.
