I would like to know if there is ANY way to get a unique key/hash/mac or any sort of identifier when trying to identify a user on the app via the fingerprint authentication provided in flutter and android?
Please note we will be having multiple users accessing the same device and none of them will have their fingerprint registered on the device before using the app.
So basically can I register users using their fingerprint(get a unique value and store in my db) and have them login with the same finger next time they visit the app ?(same finger, send the unique value to my db and check if they exist)
Any guidance in this direction is appreciated. TIA!
