BREAKING: Supabase JWT Authentication Failures - 401 Errors Identified

Supabase experiencing widespread JWT rejection issues causing 401 authentication failures. Immediate workarounds and status checks provided.

Incident Summary

Supabase is currently experiencing authentication failures with JWT token validation, resulting in 401 errors across API requests. This affects applications relying on Supabase's authentication and API services.

What's Down

Primary Impact: JWT-based authentication failing on API requests

Affected Services: Supabase REST API, potentially GraphQL endpoints

User Impact: Users unable to authenticate; applications returning 401 Unauthorized errors

Scope: Appears to affect multiple regions (confirmation pending on official status page)

How to Check If You're Affected

1. Monitor your app logs for 401 Unauthorized responses from Supabase API calls 2. Test authentication by attempting a simple authenticated request: ```bash curl -H "Authorization: Bearer YOUR_JWT_TOKEN" https://YOUR_PROJECT.supabase.co/rest/v1/your_table ``` 3. Check Supabase Status Page: https://status.supabase.com 4. Verify your JWT token is properly formatted and not expired

Immediate Workarounds

1. Token Refresh Strategy

Force token refresh on client side

Clear stored tokens and re-authenticate users

Implement retry logic with exponential backoff for failed requests

2. Temporary Service Degradation Mode

Cache recent API responses locally to maintain partial functionality

Queue failed mutations for retry when service recovers

Display graceful degradation messages to users

3. Connection Verification

Verify your Supabase project URL and API key are correct

Confirm JWT tokens include proper Authorization: Bearer header format

Check token expiration times

4. Bypass During Outage (Limited Options)

Note: I'm uncertain about current backup authentication methods Supabase supports

Consider temporary PostgreSQL direct connection if you have direct access configured

Implement local authentication fallback (uncertain if this is viable for your setup)

Alternative Services (If Extended Outage)

If this outage persists:

Firebase Authentication - Google-managed alternative

Auth0 - Enterprise authentication service

Clerk - Modern auth infrastructure

AWS Amplify - AWS-managed backend alternative

PlanetScale/MySQL + custom auth - Self-managed approach

Recommended Actions

1. Immediately: Implement retry logic and token refresh mechanisms 2. Short-term: Monitor Supabase status page and official channels for updates 3. Document: Log all affected transactions for later reconciliation 4. Communicate: Notify users of degraded service if applicable 5. Prepare: Have migration documentation ready if extended outage occurs
