I am working on a React-Native web-based application and I want to create a new style of authentication.
here what I hope to do: -
I want to scan the user Fingerprint and save it to my database, then instead of giving me username and password.
He just uses his fingerprint and it will login.
so, is there any library or anything to help me scanning the fingerprint id and get its value to be saved?
it is critical for me please HELP!

On iOS you use the Local Authentication framework. You cannot capture fingeprints, but this framework will prompt the user to authenticate biometrical (fingerprint or face) and tell you whether a valid biometric authentication occurred. You cannot distinguish between enrolled fingers – Paulw11 Jun 27 '18 at 01:20

2The answer mentioned there, they use the touch id to authenticate the user locally, they ask the phone to authenticate the user to open the app. I don't want to do it like this. I want to get the value of the touch id and keep it on my server and authenticate the user myself next time. Got it? – Ahmed Shaltout Jun 28 '18 at 17:55

This is a borderline [link-only answer](//meta.stackexchange.com/q/8231). You should expand your answer to include as much information here, and use the link only for reference. – Blue Oct 20 '18 at 18:09
