Firebase Notice: This domain is not authorized for OAuth operations in your Firebase project.
Option 1: Instant Local Fix
If you are opening from 127.0.0.1, simply open the URL using http://localhost:5500 instead! Firebase has localhost whitelisted by default.
Option 2: Add Domain in Firebase Console
- Open Firebase Console Auth Settings
- Scroll down to Authorized domains → Click Add domain
- Add:
127.0.0.1 (or your domain e.g. ggcreation25.github.io)
- Click Save and reload the page.
You can also sign in directly using Email/Password or Auto-Fill Admin Credentials with no domain restrictions!
