Is it possible to have biometric_storage to a centralized database where it can store multiple Users Fingureprints flutter

I have a flutter app with biometric authentication, currently only works with local authentication but I wanted to have all biometric information on a centralized place eg FireStore, or any other third-party storage where all devices will be submitting their fingerprints for verification. How can I achieve that as android seems to only allow local authentication using biometric?

You can't get access to any sort of biometric data from device. but you can do it differently.

For each user:

-> define unique id such as access token/username anything that is unique to user.

-> get the user enrolled for biometric authentication

-> on first time authentication, encrypt the unique id and post to the server & do whatever you wish to do. you can later use it for user authentication

-> in subsequent biometric authentication, fetch the previously stored encrypted id from server and decrypt it and authenticate against the user entered credentials.
