  1. Hi Yusuf, the tutorial is really a great contribution to the flutter development community.
    I want to ask one important question which is, “Can this project handle more than one user, or in simple words can the local auth lib save more than one or more user’s biometric data. Can we use this code in which multiple users can authenticate via this code?” or this code is for a single person.. If multiple users can be having the ability to register themselves from this app can you guide me? please reply me here or on my mail.

  2. I am wondering on how to integrate this with Backend. My use case is once user is authenticated by face id how I can communicate with backend securely so backend can validate the user and generate the token for subsequent calls.
