I have a Xamarin Forms project that uses Google Authentication as described here. On clicking "Log In", it launches a Presenter that displays the Google Log in page via web - it allows you to Choose an Account. The previously used accounts are displayed and users have the option to add another account as well. This all works fine. However, there's no way to remove an account from this list. Even if the app is uninstalled and reinstalled, the accounts still appear on the list. I have a users that share a device, so it's problematic that they can tap on their account to sign in without entering a password. Is it possible to remove accounts from the Choose an Account list?
