title: Best way to use sessionStorage in angular
body: <p>I'm pretty new to AngularJS and I try to implement a litte Ionic App as clean as possible.</p>
  
  <p>My app contains a controller for login which store the logged user in the $rootScope but I've read that using $rootScope isn't a good practices to share variables between controllers.</p>
  
  <p>So I would like to use sessionStorage and localStorage but I wonder what are the best practices about it:</p>
  
  <ul>
  <li><p>Should my ServiceLogin service write directly in storage or send data to controller which become the only who can write in storage?</p></li>
  <li><p>Can/Should I use sessionStorage variable directly in html between {{ }} tags?</p></li>
  </ul>
