- [ERR]Implement biometric authentication with fallback mechanisms for devices without fingerprint/face recognition support.
- [ERR]Ensure compliance with banking security regulations while maintaining a smooth user experience for account access.
- [ERR]Optimize app performance for users with slower network connections in rural areas.
Implemented a robust authentication layer using Android BiometricPrompt API with graceful degradation to PIN-based authentication. Used encrypted SharedPreferences and Android Keystore for secure credential storage.
val biometricPrompt = BiometricPrompt(
activity,
executor,
object : BiometricPrompt.AuthenticationCallback() {
override fun onAuthenticationSucceeded(result: AuthenticationResult) {
// Decrypt user credentials
viewModel.authenticateUser(result.cryptoObject)
}
}
