What are the differences between biometric authentication and hardware tokens?

What are the differences between biometric authentication and hardware tokens?

Biometric authentication uses unique physical traits like fingerprints or facial recognition, while hardware tokens are physical devices that generate codes for authentication.

Which method is more secure?

Both have their strengths. Biometric authentication is hard to replicate, but can be spoofed. Hardware tokens are secure but can be lost or stolen.

Are there any drawbacks to using biometrics?

Yes, privacy concerns and the potential for false positives or negatives are significant drawbacks of biometric systems.

What about the cost of implementing these systems?

Biometric systems can be expensive to implement due to the technology required, while hardware tokens are generally cheaper but may incur ongoing costs for replacements.
