biometrics authentication

Biometric authentication uses unique physical features—such as fingerprints, facial features, or voice patterns—to verify identity. Instead of passwords, the system scans these traits and compares them to stored data. This method enhances security and convenience, as biometric traits are difficult to duplicate. It’s commonly used in smartphones, security systems, and access controls to ensure that only authorized individuals gain entry or use certain services. Overall, biometric authentication offers a fast, reliable way to confirm identity based on unique biological characteristics.
