Biometric systems promise to replace reusable passwords.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Biometric authentication uses unique physical or behavioral traits to verify identity, removing the need to rely on passwords that can be reused, shared, or stolen. Because these traits are tied to the individual and aren’t something someone can easily recreate or disclose, many security discussions and vendor messages present biometrics as a path to replacing reusable passwords altogether. The idea is that login becomes linked to who you are rather than what you know, which can reduce password-based risks like reuse and credential stuffing. In practice, many systems still use biometrics alongside another factor or as a fallback option, and there are concerns about privacy, spoofing, and revocation. Still, the promotional stance that biometrics could replace passwords captures the direction many have been aiming for, hence why this statement is considered correct.
