title: Integrate oauth 2.0 server with codeigniter
body: <p>I want to integrate a oauth 2.0 server system to access my login externally</p>
  
  <p>I found  CodeIgniter-OAuth-2.0-Server in internet but that code seems to be deprecated. It would be a bad idea to integrate it with my codeigniter?</p>
  
  <p>You know of some other project oauth 2.0 server for my codeigniter?</p>
  
  <p>much thanks</p>
