title: OAuth2 Refresh Token. How to store it on client-side
body: <p>There is <em>Authorization OAuth2 Server</em> to get <em>access+refresh token</em>.
  As far as i understand, <strong>access token</strong> can be stored on <em>client-side</em>, because it has short live circle. But can <strong>refresh token</strong> be stored there? According information that I've read, there is no secure way to do it<a href="https://stackoverflow.com/questions/18280827/using-oauth2-in-html5-web-app">(here)</a></p>
  
  <p>So, I have to implement separate server-side service, just to <em>store refresh token</em>.</p>
  
  <p>Am I right? Is it only one possible way to <em>store refresh token</em>?</p>
  
  <p>P.S. Client-side: angularJS</p>
