Which statement about biometrics and passwords aligns with the discussed material?

• A. The major promise is to replace reusable passwords.
• B. Biometrics have no impact on password usage.
• C. Passwords are always superior to biometrics.
• D. None

Answer: (A)

Biometrics and passwords are often discussed in terms of shifting away from reusable passwords toward authentication based on physical characteristics. The major promise being highlighted is that biometric methods could replace the need to rely on passwords for everyday access, since a fingerprint, iris scan, or other biometric trait is something you inherently have and use, making logins smoother and less likely to be forgotten or reused across sites. This view reflects why the statement about replacing reusable passwords aligns with the material: it captures the core incentive driving biometrics—improving usability and reducing password-driven vulnerabilities. Of course, real-world use isn’t without caveats—biometrics can’t be changed like a password if compromised, there are false accept/reject risks, privacy concerns, and many systems actually use biometrics in combination with passwords or as part of multi-factor authentication. The other options aren’t supported because biometrics do impact password usage by changing how authentication is approached, claiming passwords are always superior is too absolute given the trade-offs, and saying none would ignore the clear point that biometrics are promoted as a potential replacement.
