BREAKING: Supabase JWT Authentication Failures – Immediate Workarounds

Supabase experiencing widespread 401 errors from JWT token rejections. Authentication systems affected. Workarounds and status checks inside.

Incident Status

Supabase is currently experiencing authentication failures across multiple services, with JWT (JSON Web Token) rejections causing 401 errors for authenticated requests.

What's Affected

Supabase Auth: User login/session validation

API Requests: Any authenticated API calls requiring valid JWT tokens

Real-time subscriptions: May fail with invalid auth tokens

Row-level security (RLS): Policies dependent on JWT claims

Note: Unauthenticated read operations may still function depending on your policies.

Immediate Workarounds

#### 1. Token Refresh Strategy ```javascript // Force token refresh before requests const { data, error } = await supabase.auth.refreshSession(); if (error) console.error('Refresh failed:', error); // Retry your API call after refresh ```

#### 2. Temporary Bypass (Development Only)

Temporarily disable RLS policies if non-production

Use service role key for critical operations (server-side only)

Do NOT expose service role in client code

#### 3. Fallback Authentication ```javascript // Use anon key for public queries temporarily const { data } = await supabase .from('table_name') .select('*') .limit(10); ```

#### 4. Connection Pooling Reset

Clear browser localStorage: localStorage.clear()

Restart your application

Force-clear Supabase session cookies

How to Check If You're Affected

Quick diagnostic:

1. Check Supabase status page: https://status.supabase.com 2. Test in browser console: ```javascript const { data: { user } } = await supabase.auth.getUser(); console.log(user); // null = affected ``` 3. Monitor server logs for: JWT verification failed, Invalid token, 401 Unauthorized 4. Check network tab for 401 responses on /auth endpoints

Alternatives & Workarounds

Short-term:

Switch to Firebase Authentication (if flexible)

Use Auth0 with Supabase database

Implement JWT token caching with extended expiry

Use API Gateway to inject valid tokens server-side

Interim solutions:

Cache authentication state locally with verification timestamps

Implement exponential backoff retry logic

Use session-based auth temporarily instead of JWT

Recommended Actions

1. Immediately: Deploy token refresh logic to production 2. Document: Current workarounds in your incident log 3. Monitor: Watch Supabase status dashboard continuously 4. Communicate: Notify users of potential auth issues 5. Prepare: Have Firebase/Auth0 setup ready as backup

What We Don't Know

Root cause: Exact reason for JWT rejection (server-side configuration, certificate issue, etc.)

ETA: How long Supabase team needs to resolve

Scope: If ALL JWT tokens are rejected or specific types

Regions: Whether this is global or region-specific
