BiometricPrompt with custom password

I'm currently implementing AppLock using BiometricPrompt (androidx.biometric:biometric:1.0.0-rc01)

There is an option .setDeviceCredentialAllowed(true) which uses device's password.

But I was wondering if there is a way to use this library with custom password (not from system)?

Thanks in advance.

    No, sorry. That is beyond the scope of BiometricPrompt. If you wish to use device authentication as a second factor to an app-specific password, you will need to implement the app-specific password yourself.
