title: How to authenticate to google in background?
body: <p>I have build a google authentication as shown in this blog.</p>

  <p>The problem is that it always shows an pop up so that users can login. But I want that login to happen in background where I will be passing the username and password.</p>
  <p>Are there a solution for this problem?</p>
