Fingerprint authentication from second login

User_101User_101 Member ✭✭✭

I want to implement a login screen which accepts username,password.

If user wants to use fingerprint auth from next login(and if available), fingerprint authentication should happen. I am able to implement fingerprint auth, but not sure how to do it from second login.

What should be done here? Use dependency service?

    Can't you just store the information that you were logged in once into the apps preferences?


    Then when coming onto the login screen again you check if the value is set and you show the Fingerprint:


    Or did I misunderstood something?
