Great! You've completed the setup. Now you can implement and use email authentication in your project.
Setup Google Auth
To enable Google login in your project, you need to configure the Google Auth Provider after you have completed the above steps.
For detailed steps on configuring OAuth Credentials in the Google Cloud Console and enabling the Auth Provider in the Supabase Dashboard, follow this documentation (opens in a new tab).
Here's a brief overview of the process:
- Set up a project in the Google Cloud Console (opens in a new tab).
- Configure OAuth Credentials for your application from the Google Console Dashboard.
- Enable the Google Auth Provider in the Supabase Dashboard (opens in a new tab).
Remember to securely store any client IDs or secrets provided during this process, and never expose them in your client-side code.
