Android Confirm Credential Sample
A sample that demonstrates how to use device credentials (PIN, Pattern, Password) in your app
This sample demonstrates how you can use device credentials (PIN, Pattern, Password) in your app to authenticate the user before they are trying to complete some actions.
First you need to create a symmetric key in the Android Key Store using KeyGenerator which can be only be used after the user has authenticated after the user is authenticated with their device credentials and pass KeyGenParameterSpec.
By setting an integer value to the KeyGenParameterSpec.Builder.setUserAuthenticationValidityDurationSeconds, you can consider the user as authenticated if the user has been authenticated with the device credentials within the last x seconds.
Then by calling KeyguardManager.createConfirmDeviceCredentialIntent, you can show a screen to confirm device credentials to the user.
