BREAKING: Supabase JWT Authentication Issues - 401 Errors Identified

Supabase experiencing widespread JWT token rejection errors. Immediate workarounds and status checks available.

Incident Summary

Supabase is currently experiencing authentication failures resulting in 401 Unauthorized errors related to JWT (JSON Web Token) validation and rejection across multiple services.

What's Affected

Authentication service: JWT token validation failing

API requests: Calls requiring Bearer token authentication returning 401

Real-time connections: May experience disconnection or authentication failures

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

Dashboard access: Some regions/instances reporting access issues

How to Check If You're Affected

1. API calls: Monitor for 401 Unauthorized responses with error message containing "JWT" or "token" 2. Application logs: Look for authentication rejection patterns 3. Supabase Status Page: Check [status.supabase.com](https://status.supabase.com) for official updates 4. Test endpoint: Attempt a simple authenticated request and monitor response headers 5. Dashboard: Try logging into Supabase dashboard - may show connection errors

Immediate Workarounds

Short-term (While investigating)

Temporarily disable RLS policies if non-critical, allowing public access (security risk - use cautiously)

Implement client-side retry logic with exponential backoff for failed auth requests

Cache authentication tokens locally if your application architecture allows

Switch to service role key for backend operations if available (bypasses user JWT but requires secure environment)

Queue failed requests in a database and retry after service restoration

Alternative Services (Failover)

Firebase Authentication + Cloud Firestore

Auth0 + custom database backend

AWS Cognito + DynamoDB

Your own JWT implementation using libraries like jsonwebtoken (Node.js) or PyJWT (Python)

Technical Troubleshooting

If not infrastructure-wide:

Verify JWT secret key hasn't been rotated recently

Check token expiration times (ensure not using expired tokens)

Validate JWT structure: confirm header.payload.signature format

Verify CORS and API configuration settings

Clear browser cache and re-authenticate

For developers:

```javascript // Implement retry logic const authenticatedFetch = async (url, options, maxRetries = 3) => { for (let i = 0; i < maxRetries; i++) { try { const response = await fetch(url, options); if (response.status !== 401) return response; } catch (error) { if (i === maxRetries - 1) throw error; await new Promise(r => setTimeout(r, Math.pow(2, i) * 1000)); } } }; ```

Recommended Actions

1. Monitor actively: Check Supabase status updates every 15 minutes 2. Notify users: If customer-facing, communicate outage status 3. Enable fallback auth: Switch to secondary authentication provider if implemented 4. Document: Log incident details for post-mortem analysis 5. Await official statement: Supabase support typically responds within 1-2 hours
