Hi 👋 we received this email from Google Play to update our fingerprint API to BiometricPrompt API but oct 15. We are about to release that work but it will start going live to production sometime mid-week of next week. The email reads

We recommend addressing this issue before October 15, 2023 to ensure a frictionless user experience on Android devices releasing this fall.

My question is: What would happen to the users who don't update to the latest version of our app by Oct 15th? Will they experience issues with the fingerprint API?

Note that Pixel 8 and 8 Pro have both fingerprint and face unlock that are both classified as 'Class 3' biometrics (i.e., the strongest possible): https://www.androidcentral.com/phones/google-pixel-8-face-unlock-upgrade So for apps that are using

BiometricPrompt

, they'll automatically support both fingerprint and face unlock (based on what the user has set up) whereas apps that only use the fingerprint APIs won't have that same experience.

Thank you so much for your reply @Ian Lake!
