What are the two most commonly used authentication factors in multifactor authentication? (Choose two.)

A biometric factor (something you are) is a common MFA factor but is often considered alongside, rather than definitively more common than, time-based possession factors in broad enterprise MFA deployments.

A time factor, often referring to time-based one-time passwords (TOTP), is a common form of a possession factor (something you have) in MFA, where a unique code is generated and valid for a short period.

Confidentiality factor is a security goal relating to data protection, not a distinct authentication factor.

A knowledge factor refers to something the user knows, such as a password, PIN, or security question answer, which is a fundamental component of most authentication schemes and frequently combined with other factors in MFA.

Encryption factor is a security mechanism used for data protection, not a distinct authentication factor used in multifactor authentication.
