BREAKING: Supabase JWT Authentication Issues - 401 Errors Identified

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

Incident Summary

Supabase is currently experiencing authentication failures resulting in 401 errors across services. JWT (JSON Web Token) validation is rejecting legitimate requests, affecting API access and real-time functionality.

What's Down

Primary Impact: JWT-authenticated API requests to Supabase endpoints

Affected Services: PostgreSQL REST API, Real-time subscriptions, and authenticated file storage operations

User Impact: Applications cannot authenticate users or access protected resources

How to Check If You're Affected

You're experiencing this issue if:

1. API calls return 401 Unauthorized with JWT validation errors 2. Dashboard login fails or requires re-authentication 3. Real-time listeners disconnect with authentication failures 4. Client libraries (JavaScript, Python, etc.) report token rejection

Quick test: ```bash curl -H "Authorization: Bearer YOUR_TOKEN" https://your-project.supabase.co/rest/v1/ ```

If you receive 401 errors, you're affected.

Immediate Workarounds

1. Re-authenticate and Refresh Tokens

Force logout users across your application

Trigger new authentication flows to obtain fresh JWT tokens

Clear stored tokens from localStorage/sessionStorage before re-login

This often resolves temporary token validation issues

2. Use Service Role Key (Temporary)

If available, use your service_role_key for backend operations (NOT production recommended)

Service role keys bypass RLS and JWT validation layers

Use only for critical operations during incident

3. Implement Exponential Backoff

Add retry logic with 2-5 second delays

Some tokens may resolve after brief intervals

Cap retries at 5 attempts to avoid cascading failures

4. Check Supabase Status Page

Alternative Services (Temporary Failover)

Note: I'm unsure if you have alternative infrastructure configured. Options include:

Firebase Authentication (for auth layer replacement)

Auth0 (enterprise alternative)

Cached responses from CDN if available

Read-only mode using pre-cached data

Recommended Actions

1. Immediately: Force user re-authentication 2. Short-term: Implement retry logic with backoff 3. Monitor: Watch status page and Supabase GitHub issues 4. Document: Log 401 error timestamps for post-incident analysis 5. Communicate: Notify users of temporary authentication issues

What We're Unsure About

Root cause (infrastructure issue, deployment problem, or regional outage)
