Explanation
A biometric identifier is a measurable individual characteristic - physical or behavioral - used to authenticate a user. Examples include fingerprints, iris patterns, facial geometry, voice recognition, and gait. Biometrics represent the 'something you are' authentication factor. They are not an access control model (A), a physical token for storing credentials (B) like a smart card or USB key, nor an encryption algorithm (C). Biometric authentication is valued because these characteristics are difficult to steal or replicate compared to passwords or tokens.
