The technology often used for authentication in mobile devices is biometrics. This includes methods like fingerprint recognition, facial recognition, and iris scanning, which verify a user's identity based on unique physiological traits. Biometrics enhance security by providing a more reliable authentication method compared to traditional passwords, which can be forgotten or stolen. With the proliferation of mobile devices, biometric authentication has become increasingly popular due to its convenience and efficiency. It offers a seamless user experience while maintaining a high level of security for sensitive information.
