Does Supabase Work With Auth0?
You can use Auth0 with Supabase, but you're bypassing Supabase's native auth system, which creates architectural friction and duplicates auth logic.
Quick Facts
How Supabase Works With Auth0
Supabase and Auth0 can work together, but not seamlessly. The typical pattern is to use Auth0 as your identity provider while using Supabase primarily for your PostgreSQL database and realtime features. After Auth0 authenticates a user, you obtain an ID token or access token and use it to make authenticated requests to Supabase's PostgREST API. However, this approach has downsides: you're not leveraging Supabase's built-in auth system (JWT tokens, row-level security shortcuts), requiring manual token management and RLS policy configuration. You'll need to extract user information from Auth0's JWT and synchronize it with your Supabase database, creating potential data consistency issues. The better architectural choice depends on your needs—if you need Auth0's enterprise features (SAML, MFA, social connections), accept the complexity; otherwise, Supabase's auth with custom OAuth providers via their dashboard is simpler.
Best Use Cases
Quick Setup
npm install @auth0/auth0-react @supabase/supabase-jsimport { useAuth0 } from '@auth0/auth0-react';
import { createClient } from '@supabase/supabase-js';
import { useEffect, useState } from 'react';
const MyComponent = () => {
const { getAccessTokenSilently } = useAuth0();
const [supabase, setSupabase] = useState(null);
useEffect(() => {
const initSupabase = async () => {
const token = await getAccessTokenSilently({
audience: 'https://your-supabase-url',
});
const client = createClient(
'https://your-project.supabase.co',
'your-anon-key',
{
global: {
headers: { Authorization: `Bearer ${token}` },
},
}
);
setSupabase(client);
};
initSupabase();
}, [getAccessTokenSilently]);
return <div>Connected</div>;
};Known Issues & Gotchas
JWT token mismatch: Supabase RLS expects specific JWT claims that Auth0 doesn't provide by default
Fix: Configure Auth0 custom claims rules to add `sub` and `role` claims matching Supabase's expectations, or use a custom JWT template in Auth0 Actions
User session duplication: Auth0 and Supabase manage sessions independently, causing out-of-sync logouts
Fix: Implement a logout handler that clears both Auth0 and Supabase sessions, and use Auth0's logout URL with a Supabase signout call
RLS policies don't automatically work with Auth0 tokens without proper configuration
Fix: Manually configure Supabase RLS policies to extract user ID from Auth0's `sub` claim and match against your users table
No native Supabase dashboard integration for Auth0—all user management stays in Auth0
Fix: Use Auth0's Management API to sync user metadata with Supabase, or accept managing users only in Auth0
Alternatives
- •Supabase Auth + PostgREST (use Supabase's native auth with OAuth providers, simpler and fully integrated)
- •Auth0 + Firebase Realtime Database (both enterprise-grade, Auth0's native Firebase integration)
- •Clerk + Supabase (modern auth platform designed for flexible backends, better UX than Auth0+Supabase combo)
