title: Codeigniter 3 session with redis - AUTH password
body: <p>I'm a beginner with redis. And i'm quite confused with the codeigniter 3 documentation.</p>
  
  <p>I just installed a redis server and used the ci session library with redis in my app. It works quite well ... but nothing is mentioned concerning a password auth. </p>
  
  <p>here is my config.php : </p>
  
  <pre><code>$config['sess_driver'] = 'redis';
  $config['sess_save_path'] = 'tcp://localhost:6379';
  $config['sess_cookie_name'] = 'ci_session';
  $config['sess_expiration'] = 7200;
  $config['sess_match_ip'] = TRUE;
  $config['sess_time_to_update'] = 300;
  $config['sess_regenerate_destroy'] = FALSE;
  </code></pre>
  
  <p>How am i supposed to ask for an authantification ? I suppose that everybody could access to my session table in the actual way.</p>
