What identifies users based on unique physical traits?

• A. Biometric Authentication
• B. Compliance monitoring
• C. Approval processes
• D. Access transformation initiatives

Answer: (A)

Biometric authentication uses unique physical traits to identify and verify a user. By capturing features such as fingerprints, iris patterns, facial geometry, or voice, systems create a template during enrollment and then compare future presentations of the trait to that template to confirm identity. This relies on the principle of “something you are,” offering strong, convenient authentication for CIAM environments, especially as a second or multi-factor factor. The other options aren’t about identifying people by physical traits: compliance monitoring tracks policy adherence, approval processes govern access decisions, and access transformation initiatives involve changes in how access is provisioned and managed.
