Use a
BiometricPrompt.CryptoObjectbacked by an Android Keystore key, and require successful cipher initialization/authentication before callingonSuccess.Best fix in this file:
getOrCreateSecretKey()getCipher()showBiometricPrompt(...), initialize cipher with the keystore key and call:prompt.authenticate(info, BiometricPrompt.CryptoObject(cipher))onAuthenticationSucceeded, verifyresult.cryptoObject?.cipher != nullbefore unlocking.This preserves existing behavior (unlock on valid biometric) while binding it to a hardware/keystore-backed cryptographic operation.
