title: Change user with Firebase Google user authentication
body: <p>When using Firebase Google user authentication the user is immediately logged in if they have already authorized the application and only logged in to one Google account.</p>
  
  <p>Is there a way to force the "Choose an account" dialog to appear so that the user has the opportunity to login to a different Google account or create a new one?</p>
  
  <p>Currency as far as I know the user has to manually logout of the current Google account (or login to > 1) from Google.com to make the dialog appear.</p>
