title: MVC5 Authentication filters
body: <p>What is the difference between new Authentication and previous Authorization filters?. I don't see any difference. I always used: <code>[Authorize(Roles = "Admin, User")]</code></p>
  
  <p>When would you want to use Authentication filter? and when to use Authorization?</p>
  
  <p>Can someone please explain the difference? Samples would be great. thanks</p>
