FAQ
What information do you need to fix my auth issue?
Share the exact error message you see, your app link or repo access, and your platform (Lovable, Replit, etc.). I do NOT need your actual passwords or secret keys — only project access.
My app uses both Supabase and Google OAuth — is that one order or two?
If both are broken, the Standard package covers fixing multiple integrations together. Message me first and I'll recommend the right package for your situation.
Can you set up Supabase or OAuth from scratch if I haven't configured it yet?
Yes — the Premium package includes full setup from scratch, including database schema, auth configuration, and connecting everything to your app.
