title: Use JWT to authenticate separate API Microservice
body: <p>I am developing an app using microservices in NodeJS. I have built an auth api which handles the usual registration login etc and it issues JWT's</p>
  
  <p>How do I use these to protect routes in a separate API microservice written with Express? </p>
  
  <p>Do I need to use JWT with the secret to decrypt the token in the API app?</p>
