Authorization and registration Xamarin?

Question

Android

Hello everyone, you need to write an application on Xamarin.Forms in which you need to implement authorization and user registration. Is there a link to, for example, a github program with similar functionality? To learn, understand how to correctly implement authorization and registration, server requests, etc.

Answer 1

Authorization and registration are algorithms, they do not depend on the development language. Read about HttpClient, Xamarin.Auth, you can read an article on Habré about authorization in social networks on Xamarin, about working with oauth, about open id connect

Answer 2

Example app with similar functionality:
