问题
I was trying to implement login with Google and Facebook. I have successfully implemented Facebook login with Xamarin.Auth but in the Google Login I am getting error disallowed_useragent, I know Google has changed their policy and will not allow the login using WebView but is there any other way to implement Login with Google in Xamarin.Forms (Portable)?
Thank You.

It's a new Google restriction, they do not allow using their login interface in embedded webviews anymore. Therefore you can implement authorization for your app in "Native Views" - external browsers (chrome tabs, safari etc). They will return result back to your app.
The working example for Google is here: Authenticating Users with an Identity Provider
