Overview:

React Native Fingerprint Scanner is a library for authenticating users using Fingerprint (TouchID) on both iOS and Android devices. The project is currently seeking maintainers to help continue its development. The library integrates with the Local Authentication framework on iOS and provides support for newer Android devices using the BiometricPrompt library.

Features:

• TouchID Authentication: Authenticate users using their fingerprint on both iOS and Android devices.
• Local Authentication Framework: Utilizes the Local Authentication framework on iOS for secure authentication.
• BiometricPrompt Support: Supports the new native Android BiometricPrompt library for devices running Android version 23 (M) and above.
• Legacy Support: Deprecated support for legacy Android Fingerprint API library for Samsung & MeiZu phones on older Android versions.
