title: Session between REST calls with node.js for mobile
body: <p>I have to do registration for a mobile app with node.js (express.js) backend. The registration process involves sevaral steps:
  1. provide email
  2. verify email
  3. provide personal details
  4. upload photo</p>
  
  <p>For each of these steps there should be a separate call to the server API ( possibly through REST ).
  How to keep the session so that the server knows that the consecutive calls come from the same client ? This is a mobile app so cookie based session won't work I think. Could you guide me somehow ? Is using a JWT token the right way to go ?</p>
