Firebase Auth Manager

Manage Firebase Authentication configuration via the Identity Toolkit Admin API v2. No Firebase Console UI needed.

Prerequisites

• gcloud CLI authenticated (gcloud auth login)
• Editor/Owner role on the Firebase project
• Know your Firebase Project ID
• Billing must be linked to the GCP project (required for Identity Platform initialization)

First-Time Initialization (CRITICAL)

If the project has never had Firebase Auth enabled, all Admin API v2 calls will return CONFIGURATION_NOT_FOUND. You must initialize Identity Platform first:

Step 1: Enable the Identity Toolkit API

gcloud services enable identitytoolkit.googleapis.com --project=${PROJECT_ID}
