Obtaining/using Firebase JWT

Question

Early into Firebase docs and really liking it so far. Being n00b, a conceptual question here - is the (JWT) token generated by Firebase authentication accessible client-side?

I'm looking to call some external service and want to leverage JWT as the security mechanism. So:

• authenticate user using Firebase built-in providers (purely client side)
• obtain Firebase JWT (my question)
• pass this JWT as/whenever needed, to external service and verify it (using my app FBase secret) for "access" to external service

In essence, leverage existing Firebase mechanisms as a form of "gateway" to external service(s).

I saw an old answer here - "....token to survive page reloads, then you need to store it in some way so the client..." - is this token the JWT?

Thanks!

Answer 1

This is the right way to obtain firebase JWT token

firebase.auth().currentUser.getToken().then(function(token){
  console.log(token);
});
