 ## Validate cookies
 Next, you probably want to validate user authentication of non-logged in users in all controllers (note: authentication is only attempted once per session). This makes sure that a user with a valid token cookie will be logged in. To do that, place something like the following in your `AppController`'s `beforeFilter`. Note that you might also have to make changes to the current identification method you are performing. See the [next section](#create-token-cookies).
