Biometrics Support for Multiple Users in the app(Token Based)

@tnorbye @DanAlbert @keyboardsurfer @nic0lette @yrezgui

Supporting Multiple Users Fingerprint Authentication in the app - How to get Unique key/id from Finger-Print Authentication API inside the app(idea is to map and store server tokens per user in the app ex.. one for user A and one for user B, etc....) and later the idea is to perform just biometrics authentication to retrieve respective user token for server calls.

Our business need is to register/authenticate multiple users to use separate token for each user

Does the API provide support to detect which user, A or B or just logged in(like thumbs up or down)

Is there any way for an app to access the fingerprint data to be able to save it or use across the devices(if we share multiple devices among multiple users)

Highly appreciate your help

No file, test, or entry point is named. The issue asks whether Android biometric APIs expose user identity or fingerprint data and how separate tokens could be mapped, but it provides no implementation target or completion criteria.
