title: Why should I save oauth2 access token?
body: <p>When I need only grant from google for email id.Instead of saving access token. Is it better to save user details in db.</p>
  
  <p>Instead saving access token and retrieving data from oauth server (google or facebook, etc.)  with Api call </p>
  
  <p>Is it right method saving user information when first authentication and retrieving from database. </p>
