title: Auth0: How to enable silent authentication in Hosted Login Page?
body: <p>I'm using hosted screen of Auth0. I want the following scenario to work-</p>
  
  <ul>
  <li>Let's say I have 2 apps- app1 and app2. </li>
  <li>One of the users signed in by providing email+password in app1.</li>
  <li>User then navigated to app2.</li>
  <li>Auth0 detected that the user has already signed in, so it redirects the user back to app2 WITHOUT having her signed in again.</li>
  </ul>
  
  <p>But what I'm facing is this screen-</p>

  <p>How can I save my user this additional click? How do I implement silent authentication? I know that you have to pass <code>prompt=none</code> to <code>/authorize</code> api, but since I'm not manually calling the api, how do I make the lock call <code>/authorize</code> with <code>prompt=none</code>?</p>
