Getting "disallowed_useragent" error using Google authentication on Xamarin Android



I was using Auth0 component for Xamarin Forms app. It was working perfectly to authenticate against Google and Facebook. Recently it started getting a disallowed_useragent error page when I try to login on Android using Google.

Looks like it is related to latest Google authentication changes. Auth0 xamarin component hasn’t been updated for 2 years. Any workarounds? The application is about to go live and now we are getting push-backs because of this.


We have released a new SDK that is compatible with the supported approaches from Google, but this will require changes to your application in order to make use of the way of doing things.
