title: Different types of facebook access token
body: <p>I a bit confused. I'll be glad if someone could clarify it to me -</p>
  
  <p>What are the differences between the the token that I get in the following ways:</p>
  
  <ol>
  <li>Getting a token in this way: <code>https://graph.facebook.com/oauth/access_token?
  client_id=YOUR_APP_ID
  &amp;client_secret=YOUR_APP_SECRET
  &amp;grant_type=client_credentials</code></li>
  <li>Versus getting a token using Javascript SDK - <code>FB.getAuthResponse()['accessToken']</code></li>
  </ol>
  
  <p>They both look different, and I don't understand which should I use.</p>
  
  <p>Thanks!</p>
