Biometric Prompt
Biometric Prompt is an Android framework API introduced in Android 9 (Pie) that provides a standardized, secure, and user-friendly interface for biometric authentication (e.g., fingerprint, face, iris) in Android apps. It abstracts hardware-specific details and handles the complexity of biometric operations, allowing developers to integrate authentication with minimal code. The framework supports multiple biometric modalities and enforces security best practices, such as encryption and user consent.
Developers should use Biometric Prompt when building Android apps that require secure user authentication, such as banking apps, password managers, or any application handling sensitive data. It simplifies compliance with Android's biometric security standards and ensures a consistent user experience across different devices and Android versions. Use it to replace deprecated APIs like FingerprintManager and to support modern biometric features like face recognition.
