Why is biometric authentication considered a secure method?

Biometric authentication is considered a secure method primarily because it relies on unique physical traits for verification. Each individual's biometric data, such as fingerprints, facial recognition, or iris patterns, is distinct, making it incredibly difficult for someone to impersonate another person. This uniqueness acts as a strong barrier against unauthorized access since these traits cannot be easily replicated or guessed, unlike passwords or PINs which can be forgotten, stolen, or shared.

Additionally, biometric traits are inherently linked to the individual, meaning that users do not need to remember or regularly change these identifiers like they would with passwords. This reduces the risk associated with password management and user errors in selecting secure passwords. Overall, the reliance on biometric traits enhances security by providing a level of user verification that is both convenient and difficult to compromise.
