Explanation
Biometrics authenticates users based on 'what you are' - unique physical attributes (fingerprints, iris patterns, facial geometry) or behavioral traits (keystroke dynamics, gait, voice patterns). 'What you know' (passwords, PINs) and 'what you have' (tokens, smart cards) are the other two authentication factors, but neither is biometric. Therefore, the statement that a user can be authenticated by what they know is FALSE in the context of biometrics.
