This is a security feature of your system because it is not normal to do quick biometric unlocks several times in a row. I think it just comes back after...

In older versions of Android, Device credential unlocking is not related to the Biometric API but in newer versions it is. As you have a recent device, I deduced that...

Thanks for the detailed feedback, it helps me understand the problem a little better. The thing is that I can't reproduce it, as you say, the error displayed is not...

OK, it's weird, but it gives more information. I just looked at the andOTP code, it does use the Keystore but not yet in the same way, it uses it...
