How do I get the current user's access token in AngularFire2?

Question

In AngularFire you were able to access the providers (e.g Google) accessToken for the authenticated user.

There does not seem to be a way to access this with AngularFire2?

On initial login say like this:

this.af.auth.subscribe(user=> {
  if (user) {
    console.log(user.google);
  }
});

It will log out the idToken, accessToken, provider, But (on a page refresh) subsequently will log out the standard details (uid, displayName etc....) And the accessToken is not an accessible property?

Is there a way to access the current users accessToken?

Answer 1

getToken is deprecated now. You should use getIdToken instead:

this.af.auth.currentUser.getIdToken(true)
  .then((token) => localStorage.setItem('tokenId', token));

Answer 2

The access token is only accessible when the user first signs in. From the Firebase migration guide for web developers:

With the Firebase.com Authentication API, you can easily use the provider's access token to call out to the provider's API and get additional information. This access token is still available, but only immediately after the sign-in action has completed.

var auth = firebase.auth();

var provider = new firebase.auth.GoogleAuthProvider();
auth.signInWithPopup(provider).then(function(result) {
  var accessToken = result.credential.accessToken;
});

So it is indeed not available on a page refresh. If you want it to remain available, you will need to persist it yourself.

With AngularFire2, you can get the token like this :

this.af.auth.getToken() // returns a firebase.Promise<any>

If you want to get an ES6 Promise instead, just use

Promise.resolve()
  .then(() => this.af.auth.getToken() as Promise<string>)

Answer 4

This works for me:

this.af.auth.getAuth().auth.getToken(false);//true if you want to force token refresh

You can put it into a Service and then you can get the token like this:

this.authService.getToken().then(
  (token) => console.debug(`******** Token: ${token}`));

Getting the auth token from storage in angularfire2

JSON.parse(JSON.stringify(this.afAuth.auth.currentUser)).stsTokenManager.accessToken

Answer 6

With AngularFire2 : ( eg : registering user with email and password combo. )

import { AngularFireAuth } from 'angularfire2/auth';
model : any = {} ;
private afAuth : AngularFireAuth,

regWithEP () {
    this.afAuth.auth.createUserWithEmailAndPassword(this.model.email, this.model.password).then((user) => {
    /* IMPORTANT !! */
    /* EXPLICIT CHECK IF USER IS RETURNED FROM FIREBASE SERVICE !! */

          if (user) {
            console.log(user);
            /* Here user is available and is the same as auth.currentUser */

            this.afAuth.auth.currentUser.getToken().then((token) => {

            //token is available here
            //set token to currentUser, signIn , re-direct etc.
            });
        }
    });
}
