title: Any solution for OAuth Google without webviews
body: <blockquote>
    <p>I'm developping an app in which I'd like the user to log with fb or google account. So far I've been using Xamarin Auth which provides a OAuth authentification with webviews.</p>
  </blockquote>
  
  <p>As I want to realease the app on markets, I checked the future deprecation of this component. Google made an annoucement saying that they will block any OAuth in webviews from April 20th 2017 ...</p>
  
  <p>Have you find a solution to Xamarin Auth for google sign in ?</p>
  
  <p>I've seen a component for FireBase published by xamarin 25 days ago ... but I wonder if it will work for forms as it is a xamarin android component ... And I'd like to keep the logic that "forms is crossplatform" and I do not want to use a plugin for each project.</p>
  
  <p>I've been seeking the web but no solutions...</p>
  
  <p>I'm glad if someone's found something or a workaround without components if there are none ..</p>
