title: Token Authentication vs. Cookies
body: <p>What is the difference between token authentication and authentication using cookies?</p>
  
  <p>I am trying to implement the <a href="https://github.com/heartsentwined/ember-auth-rails-demo/wiki">Ember Auth Rails Demo</a> but I do not understand the reasons behind using token authentication as described in the <a href="https://github.com/heartsentwined/ember-auth/wiki/FAQ">Ember Auth FAQ</a> on the question "Why token authentication?"</p>
