Google OAuth User Authentication Problem

[Owen Densmore]

The Firebase doc for JAVASCRIPT WEB GUIDE Google Authentication

  https://www.firebase.com/docs/web/guide/user-auth.html

includes an examble of OAuth config w/ Google.

  https://www.firebase.com/docs/web/guide/login/google.html

which then points me to Google to create an app

  https://cloud.google.com/console

that then logs me in to the Google Cloud Platform console

  https://console.cloud.google.com/home/dashboard

From there on, the Firebase OAuth example deviates from what I see on Google.

FB seys: click the Create Project button. There isn't one. Instead there are several Google dev products in square panels. And so on. They likely have updated their site.

Is there a more recent FB OAuth example for Google?

Hey Owen,

It indeed looks like the flow in the Google developer console is slightly different now. The "Create a project" link is now in the Projects drop-down in the top menu bar. The drop-down will either say "Select a project" or show the name of your current project.

That worked, thanks. So I now have project started:

  Name: FirebaseAuth ID: firebaseauth-1146 Number: nnnnnnnnnnnn

Then I looked for the Credentials mentioned in the FB Google OAuth docs. Took a while with the new UI .. it was under API Manager. This give me access to all the fields FB mentions.

So I completed the configuration, using the URLs FB provides for Authorized JavaScript origins & Authorized redirect URIs. I also updated the FB Google entries to match.

I then tried

  ref.authWithOAuthPopup("google", authHandler);

but I got an odd error.  My Authorized redirect URIs was:

https://auth.firebase.com/v2/backspaces.firebaseio.com/auth/google/callback

but the error shows

https://auth.firebase.com/v2/backspaces/auth/google/callback

.. i.e. backspaces.firebaseio.com was truncated to just backspaces which failed.

I really don't know what's up, but my guess the FB docs and the new Google console are the problem?

Here's the error text:

Error: redirect_uri_mismatch

Application: Backspaces FB Auth Test

You can email the developer of this application at: <my name>@gmail.com

The redirect URI in the request: https://auth.firebase.com/v2/backspaces/auth/google/callback did not match a registered redirect URI.

That’s all we know.

Get rid of "firebaseio.com" from your callback URL. Just use your Firebase app name (that is, "backspaces").
