Which of the following best describes a Type 3 authentication factor?

• A. A password or PIN
• B. A physical device like a smartcard
• C. A fingerprint or facial recognition
• D. A combination of letters and numbers

Answer: (C)

A Type 3 authentication factor refers to something that is inherent to the user and relates to biometrics. This includes characteristics that are specific to the individual, such as fingerprints, facial recognition, iris scans, or voice recognition. These biometric measures are unique to each person, making them a strong form of authentication because they are much harder to replicate or steal compared to knowledge-based factors (such as passwords) or possession-based factors (such as smart cards). In this context, the option highlighting fingerprint or facial recognition accurately captures the essence of Type 3 factors. They rely on verifiable physiological or behavioral traits, which are utilized for confirming an individual's identity based on their physical attributes. This is distinct from other choices, which either represent knowledge or possession factors rather than biometric data.
