“Biometric authentication” enhances security by using unique physical characteristics of individuals to verify identity. This technology includes fingerprint recognition, facial recognition, and iris scanning, providing a more secure alternative to traditional passwords. Biometric data is inherently difficult to replicate or share, making unauthorized access much harder. By implementing biometric systems, organizations can improve access control and reduce the risk of data breaches. This method also streamlines user experiences by eliminating the need for memorizing complex passwords or PINs while maintaining a high level of security.
