Which term refers to authentication using physical characteristics such as fingerprints or facial recognition?

• A. Biometric security
• B. Password-based authentication
• C. Two-factor authentication
• D. Token-based authentication

Answer: (A)

Biometric security authenticates a person using unique physical traits such as fingerprints or facial recognition. These traits are inherent to an individual and are difficult to imitate, which makes this method a strong way to verify identity. Because it relies on something you are rather than something you know (like a password) or something you have (like a token), it stands out from password-based or token-based methods. Two-factor authentication can include biometric as one of its factors, but the core idea described here is the use of intrinsic physical characteristics for authentication.
