title: Is there a way to use an own frontend instead of keycloak login?
body: <p>I want to use an Angular >4 app that calls REST endpoints from Keycloak >4 to login.</p>
  
  <p>Spoiler: No, I don't want to use a Keycloak theme, because Freemarker templates are far to static. I need some dynamic ressources and CDN magic.</p>
  
  <p>So I used the "…/auth/realms/REALM/protocol/openid-connect/token" endpoint and get this as resonse:</p>
  
  <pre><code>{ 
    "access_token": "ey…"
    "expires_in":60,
    "not-before-policy":0,
    "refresh_expires_in":1800,
    "refresh_token":"ey…",
    "session_state": "…"
    "token_type":"bearer"
  }
  </code></pre>
  
  <p>I don't really can figure out what to do with this <code>access_token</code> or <code>session_state</code>. Nether did I find an example to doing this.</p>
