What does biometrics authentication rely on?

Biometrics authentication relies on unique physical characteristics of individuals for identification. This method takes advantage of traits such as fingerprints, facial recognition, iris patterns, or voice recognition, which are unique to each person. The primary advantage of using biometrics is that these characteristics are inherently linked to the individual and cannot be easily replicated or stolen, making biometric authentication a highly secure method.

Unlike knowledge-based authentication methods, which depend on a person remembering information like passwords or PINs, biometric authentication provides a more advanced layer of security as it directly ties to a physical attribute. This reliance on physical traits enhances security because these identifiers are much more difficult to forge than passwords or security tokens which can be intercepted or shared.

While device security features and security tokens may enhance security and protect against unauthorized access, they do not fall within the scope of biometric authentication, which is specifically concerned with the use of physical characteristics for verifying identity.
