title: NodeJs express-session options
body: <p>I want to create a login system by using the express-session module. I am not sure if I does all correct and I am confused by the secret option. My currently initalize for the express-session is this:</p>
  
  <pre><code>app.use(session({
     secret: 'important',
     resave: true,
     saveUninitialized: true,
     genid: function(req) {
         return uuidv4();
     }
  }));
  </code></pre>
  
  <p>And I´ve read that the secret parameter is just for cookies (<a href="https://github.com/expressjs/session" rel="nofollow noreferrer">Link</a>) but I don´t want to use cookies. I just want to use sessions.</p>
  
  <p>Can I now ignore the secret parameter?</p>
