Fix Your AI-Built Supabase Auth Integration
Authentication built into Supabase with RLS integration. AI tools skip Row Level Security policies and mishandle server-side auth in Next.js.
Common Supabase Auth issues we find
Problems specific to AI-generated Supabase Auth integrations.
Row Level Security policies not created or too permissive
AI-generated code creates tables without RLS enabled or adds overly permissive policies like 'true' for all operations, defeating the purpose of Supabase Auth.
Using anon key for server-side operations
Generated code uses the anon key in server-side API routes instead of the service role key, causing operations to fail or bypass RLS unintentionally.
Auth state not synced between client and server in Next.js
AI tools use createBrowserClient() everywhere instead of properly configuring createServerClient() with cookie-based sessions for Server Components and Route Handlers.
Email confirmation flow not handled
Generated code calls signUp() and immediately redirects to the dashboard without waiting for email verification, leading to unverified users accessing protected content.
Missing auth middleware for protected routes
AI tools check auth state on individual pages instead of using Next.js middleware to refresh sessions and protect routes at the edge.

Frequently asked questions
Why is my Supabase auth working locally but not in production?
The most common cause is missing or incorrect Site URL and Redirect URL configuration in the Supabase dashboard. AI tools only configure the local environment. You also need to ensure cookies are configured correctly for your production domain.
Are my Supabase RLS policies secure in my AI-generated code?
Usually not. AI tools either skip RLS entirely or create policies that check auth.uid() but miss edge cases like service role access, cross-user data access via joins, or policies on storage buckets. We audit every policy against your actual data access patterns.
How do I fix Supabase auth session issues in Next.js App Router?
You need three separate Supabase clients: createBrowserClient for Client Components, createServerClient for Server Components and Route Handlers (with cookie access), and middleware to refresh expired sessions. AI tools typically only create one client.
