Your use case

What would you like to do?

Improve security against attacks using biometric authentication.

Why would you like to do it?

While the new lock screen feature is more secure that the previous one, there is still room for improvement.

How would you like to achieve it?

There are a couple of measures that one of our clients asked us to implement:

  1. Enforce CryptoObject usage and validation after biometric auth succeeds.
  2. Add setUnlockedDeviceRequired(true) to the biometric/system key so it can only be used while the device is unlocked.

Have you considered any alternatives?

No, the new measures seem reasonable.

Additional context

No response

Are you willing to provide a PR?

Yes
