An example of a biometric authentication method is fingerprint recognition. This technology uses the unique patterns found in a person's fingerprints to verify their identity. Fingerprint scanners are often used in smartphones, security systems, and access control devices due to their accuracy and speed. Biometric authentication offers a more secure alternative to traditional passwords, as fingerprints are difficult to replicate or steal. As a result, this method enhances security measures and user convenience across various applications.
