Tips

Google will send you an email, and you'll need to respond to initiate the process. Ensure that your domain is verified with Google Search Console; You can manage that step now. Logging in with Google already works on localhost. On production, it will also work but will show a warning until you're verified, which usually takes a few days.

Ready for production?

In the Supabase dashboard, go to [Authentication], then [URL Configuration]. Add https://your-domain.com into [Site URL]. Also, include https://your-domain.com/* in [Redirect URLs].
