Cursor auth

Supabase Authentication Integration Broken

After Cursor refactored your Supabase authentication integration, login/signup stops working. Users cannot authenticate or their session isn't being maintained.

Supabase client initialization or auth flow was broken.

Error Messages You Might See

Invalid Supabase credentials Auth session not found Signup failed Login returns error
Invalid Supabase credentialsAuth session not foundSignup failedLogin returns error

Common Causes

  1. Supabase client not initialized with correct URL and key
  2. signUp/signIn methods removed or refactored incorrectly
  3. Session management broken, not persisting auth state
  4. Auth listener not set up, session changes not detected
  5. Environment variables for Supabase not set

How to Fix It

Initialize client: createClient(url, anonKey). Sign up: await supabase.auth.signUp({email, password}). Listen to session: supabase.auth.onAuthStateChange(). Store session in state/context. Verify env vars NEXT_PUBLIC_SUPABASE_URL and _KEY.

Frequently Asked Questions

How do I persist auth across page reloads?

Supabase handles this. Call getSession() on app load to restore session from storage.

What's the difference between anon and service keys?

Anon key: client-side (safe to expose). Service key: server-side only (secrets). Use appropriate key based on context.
