🚨 [BUG] Firebase Authentication Error: “auth/unauthorized-domain” on Login and Signup Pages

[codewithyasho]

Description

When trying to sign up or log in on the deployed website (https://aistockanalyzer.onrender.com/), Firebase authentication fails with the error message:

Firebase: Error (auth/unauthorized-domain).

This happens for both Google Sign-In and Email/Password methods, preventing users from logging in or creating an account.

Where is the issue?

Steps to Reproduce

Example:

1. Go to https://aistockanalyzer.onrender.com/
2. Click on Signup or Login
3. Try to sign in using Google or Email/Password
4. Observe the error message:
   Firebase: Error (auth/unauthorized-domain).

Screenshots

Environment

• OS: Windows 11
• Browser: Microsoft Edge (Chromium)
• Device: Desktop

Additional Notes

The issue occurs because the deployed domain (aistockanalyzer.onrender.com) is not added to Firebase → Authentication → Settings → Authorized Domains.
To fix this, the admin should add the Render domain to the Firebase authorized domains list.

Hey @SrigadaAkshayKumar 👋, I noticed that the Firebase Authentication on the deployed site is throwing an auth/unauthorized-domain error when trying to sign up or log in.

It seems the deployed Render domain (aistockanalyzer.onrender.com) isn’t added to Firebase’s Authorized Domains list.
Could you please add it under
Firebase Console → Authentication → Settings → Authorized Domains

Once it’s added, I’ll verify and confirm if the issue is resolved.
