BREAKING: Supabase JWT Authentication Issues - 401 Errors Identified

Supabase experiencing widespread JWT rejection errors. Authentication services degraded. Immediate workarounds and recovery steps inside.

Incident Summary

Supabase is currently experiencing authentication failures resulting in 401 JWT rejection errors across multiple services. This affects API requests, real-time connections, and database access for applications relying on Supabase authentication.

What's Down

Primary Impact: JWT token validation and authentication layer

Affected Services: API requests, real-time subscriptions, row-level security (RLS) enforcement

Scope: Appears to be affecting multiple regions (specific regions TBD - monitor status page)

User Impact: Applications cannot authenticate users; API calls return 401 Unauthorized errors

How to Check If You're Affected

1. Test authentication: Try logging in or making an authenticated API request 2. Check browser console: Look for 401 responses on auth endpoints 3. Review logs: POST /auth/v1/token or similar endpoints returning 401 4. Monitor real-time: Subscriptions will fail to establish 5. Check official status: https://status.supabase.com

Immediate Workarounds

Workaround 1: Token Refresh (Short-term)

Force users to re-authenticate

Manually trigger session.refresh() in your application

Clear browser cache/local storage and re-login

Note: *Uncertain if this will succeed if service is fully degraded*

Workaround 2: Implement Client-Side Caching

Cache last-known-good JWT tokens temporarily

Store user session data locally

Implement retry logic with exponential backoff

Queue failed requests for replay when service recovers

Workaround 3: Fallback Authentication

If you maintain a secondary auth system, temporarily redirect there

Implement basic session tokens separate from Supabase JWTs

Use API key authentication for non-user operations (if available and secure)

Workaround 4: Database Queries

If direct database access is available, bypass Supabase auth temporarily (evaluate security implications)

Use connection pooling with stored credentials

*I'm uncertain about security implications here - proceed carefully*

Alternatives During Outage

1. Firebase Authentication - Quick migration for auth layer 2. Auth0 - Enterprise alternative with similar JWT workflows 3. Clerk - Modern auth platform with similar feature set 4. AWS Cognito - AWS ecosystem alternative 5. Custom JWT Server - Temporary self-hosted auth (requires infrastructure)

Recovery Checklist

☐ Monitor Supabase status page for updates

☐ Implement retry logic (wait 30-60 seconds between attempts)

☐ Notify users of authentication issues

☐ Test token refresh once service shows green

☐ Verify RLS policies are enforced after recovery

☐ Check for data consistency issues

☐ Review logs for failed requests (for replay)

Note on Uncertainty

This report identifies the JWT rejection issue clearly, but specific details remain unclear:
