Configure Firebase for WebApp

I’ve built a web application and now need the Firebase side wired up so everything runs securely and smoothly. The project is already registered in the Firebase console; what’s missing is proper configuration and integration.

Scope of work
• Enable and fully configure Firebase Authentication for three sign-in options:
– Email & Password
– Google social login
– Phone number verification
• Set up the Firebase Database service (Cloud Firestore or Realtime Database—please advise which fits best) with secure read/write rules tailored to my app’s user roles.
• Supply any required API keys, OAuth consent-screen details, and redirect URIs, then connect them to the existing front-end so I can call Firebase methods straight from my JavaScript code.
• Provide a short hand-over doc or Loom walk-through showing where each configuration lives and how to extend it in the future.

Acceptance criteria
1. I can create an account and sign in with every chosen method without console errors.
2. A test document can be created, read, updated, and deleted from the database while respecting security rules.
3. All configuration is committed to my Git repo via a clean pull request.

If you have recent experience with Firebase Auth, Google OAuth, and database security rules, let’s get this live quickly.
