Which term identifies users based on unique physical traits?

• A. Biometric Authentication
• B. One-Time Password
• C. Access transformation initiatives
• D. Compliance monitoring

Answer: (A)

Biometric authentication is about using measurements of a person’s body—like fingerprints, facial features, iris patterns, or voice—to verify who they are. Because these traits are unique to each individual, they provide a strong way to confirm a user’s identity in CIAM systems. The other options don’t describe using physical traits: a one-time password is a temporary code, not a biometric measure; and access transformation initiatives along with compliance monitoring refer to governance and process improvements, not identity verification through biometrics.
