Google Login works with WordPress users but does NOT create Firebase Auth users (critical issue)

App Login
1

Hello AppMySite Team,

I’m facing a critical issue with the login system, and I need a clear technical explanation and solution.

Here is my setup and problem in detail:

  • I am using AppMySite mainly as a wrapper / framework to publish a mobile app.

  • The app loads a mobile-only WebView page from my WordPress site.

  • Google Login popup appears correctly (account chooser screen).

  • After selecting a Google account, the user is successfully registered/logged in inside WordPress (wp_users).

  • However, no user is created in Firebase Authentication.

Important points:

  • Firebase project is fully configured.

  • SHA1 & SHA256 fingerprints are added.

  • Google Sign-In is enabled in Firebase Authentication.

  • Service accounts are configured.

  • Firebase Cloud Messaging is already working.

  • The app is correctly linked to Firebase.

Despite all of this:

  • Firebase Authentication → Users remains empty.

  • Login events are not reflected in Firebase at all.

  • Firebase cannot recognize authenticated users, which breaks:

    • User-based notifications

    • Future subscriptions

    • Premium/free user logic

From my understanding:

  • AppMySite Google Login authenticates users directly with WordPress, not via Firebase SDK.

  • This means Firebase is never notified that a login occurred.

My questions:

  1. Does AppMySite Google Login use Firebase Authentication internally, or is it completely separate?

  2. If it does NOT use Firebase Auth, is there any supported way to:

    • Sync authenticated users with Firebase?

    • Or trigger Firebase Auth after successful login?

  3. Is it possible to fully disable AppMySite’s login and use a custom Firebase-based login instead (Google / Apple / Phone OTP) without breaking the app?

  4. Are there plans to support Firebase-first authentication flows?

This issue blocks my entire roadmap, because I need:

  • Firebase as the single source of truth for authentication

  • WordPress users to be created after Firebase login, not the opposite

I would really appreciate a clear technical answer, not a generic setup guide, because all standard configurations are already done.

Looking forward to your response.
