Android Biometric Prompt
Android Biometric Prompt is a system-provided dialog that standardizes biometric authentication (fingerprint, face, iris) across Android devices. It provides a consistent user interface and handles the underlying hardware interactions, simplifying secure authentication implementation for developers. It's part of the AndroidX Biometric Library and supports biometric and device credential (PIN/pattern/password) authentication.
Developers should use Android Biometric Prompt when building Android apps that require secure user authentication, such as banking apps, password managers, or any app handling sensitive data. It's essential for compliance with security best practices and provides a user-friendly, standardized experience across different Android versions and device manufacturers. Use it to replace deprecated APIs like FingerprintManager and ensure future compatibility with new biometric modalities.
