<p>You can get access token using <code>FB.getAuthResponse()['accessToken']</code>:</p>



<pre class="lang-js prettyprint-override"><code>FB.login(function(response) {
   if (response.authResponse) {
     var access_token =   FB.getAuthResponse()['accessToken'];
     console.log('Access Token = '+ access_token);
     FB.api('/me', function(response) {
     console.log('Good to see you, ' + response.name + '.');
     });
   } else {
     console.log('User cancelled login or did not fully authorize.');
   }
 }, {scope: ''});
</code></pre>

<p>Edit:
Updated to use Oauth 2.0, required since December 2011. Now uses <code>FB.getAuthResponse();</code>
If you are using a browser that does not have a console, (I'm talking to you, Internet Explorer) be sure to comment out the <code>console.log</code> lines or use a log-failsafe script such as:</p>

<pre class="lang-js prettyprint-override"><code>if (typeof(console) == "undefined") { console = {}; } 
if (typeof(console.log) == "undefined") { console.log = function() { return 0; } }
</code></pre>
