Biometric Authentication
Biometric authentication is a security process that verifies a user's identity using unique biological characteristics, such as fingerprints, facial features, iris patterns, or voice. It replaces or supplements traditional methods like passwords or PINs by leveraging physiological or behavioral traits that are difficult to forge or steal. This technology is widely used in devices like smartphones, laptops, and access control systems to enhance security and user convenience.
Developers should learn biometric authentication to implement secure, user-friendly authentication systems in applications requiring high security, such as banking apps, healthcare platforms, or enterprise software. It reduces reliance on weak passwords, minimizes fraud risks, and improves user experience by enabling quick, seamless access. Use cases include mobile app login, physical access control, and identity verification in compliance-driven industries like finance and government.
