  • In your Firebase project, go to the "Authentication" section.

  • Click the "Sign-in method" tab.

  • If you want to use Firebase's web SDK for authentication, follow these steps:

    • In the Firebase console, click "Add App" and select "Web".

    • Give your web app a nickname (e.g., "My Web App").

    • Click "Register App".

    • You will see your Firebase configuration details, including the apiKey.

4. Get Your API Key:

  • In the Firebase console, go to "Project settings" > "General".

  • Scroll down to "Your apps" and click on the web app you registered (if you did).

  • You will find the apiKey value. Copy this value.

5. Set the API Key in the Extension:
