FingerprintManager
FingerprintManager is an Android API (part of the Android framework) that provides a standardized way for apps to authenticate users using fingerprint biometrics on Android devices. It handles the hardware interaction with fingerprint sensors and manages the authentication flow, including enrollment, verification, and error handling. This API was introduced in Android 6.0 (Marshmallow) and is part of the Android BiometricPrompt system for secure user authentication.
Developers should learn and use FingerprintManager when building Android apps that require secure user authentication, such as banking apps, password managers, or any application handling sensitive data. It provides a convenient and secure alternative to passwords or PINs, enhancing user experience by enabling quick and reliable biometric verification. Use cases include unlocking app features, authorizing payments, or accessing encrypted data stored locally on the device.
