title: Does expressjs automatically generate a new session id?
body: <p>So I'm creating an express application and I'm using express-session. I'm new to express so I will clarify anything if needed.</p>
  <p>I was reading a medium article and came across this:</p>
  <blockquote>
  <p>Genid - A function to generate a new session ID. The default value is a function that uses the uid-safe library to generate IDs.</p>
  </blockquote>
  <p>I'm using express-session so do I need to generate IDs for each user or does express-session do it for me?</p>
