BREAKING: Supabase JWT Authentication Issues - 401 Errors Identified

Supabase experiencing widespread 401 JWT rejection errors. Immediate workarounds and status inside.

Incident Summary

Supabase is currently experiencing authentication failures resulting in 401 Unauthorized errors related to JWT token validation. This affects applications relying on Supabase authentication across REST API calls and real-time connections.

What's Affected

Authentication Layer: JWT token validation is rejecting valid tokens

REST API Requests: Calls requiring Authorization: Bearer <token> headers failing

Real-time Subscriptions: WebSocket connections with auth tokens being rejected

Severity: High - blocks authenticated access to protected resources

Status: Ongoing investigation

How to Check If You're Affected

1. API Requests: Check logs for 401 Unauthorized responses 2. Browser Console: Look for failed fetch requests with 401 status 3. Real-time: Supabase client connection state shows CHANNEL_ERROR 4. Verification: Test a simple authenticated request: ```bash curl -H "Authorization: Bearer YOUR_TOKEN" https://your-project.supabase.co/rest/v1/users ```

Immediate Workarounds

Workaround 1: Implement Client-Side Token Refresh (Recommended)

```javascript const { data, error } = await supabase.auth.refreshSession(); if (error) console.log('Refresh failed'); // Retry request with new token ```

Workaround 2: Use Service Role Key (Temporary Only)

Note: This bypasses RLS policies - use only for critical operations: ```javascript const supabaseAdmin = createClient(URL, SERVICE_ROLE_KEY); // Execute queries - but this exposes admin access ```

Workaround 3: Implement Token Caching & Validation

Store tokens locally with expiry timestamps

Validate tokens before making requests

Pre-emptively refresh before expiry

Workaround 4: Switch to Anonymous Access (Limited)

If your application supports it: ```javascript const { data } = await supabase .from('public_table') .select('*') .limit(10); ```

Alternative Solutions

1. Implement Custom Auth Endpoint: Create your own token validation service 2. Use Firebase Auth: Temporary migration for critical apps 3. GraphQL API: Some users report REST-specific issues - test GraphQL endpoints 4. Database Connection Pooling: Access PostgreSQL directly if available in your plan
