BREAKING: Supabase JWT Authentication Issues - 401 Errors Identified

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

Incident Summary

Supabase is currently experiencing authentication failures resulting in 401 errors across JWT-based requests. This affects API calls, real-time subscriptions, and client-side authentication flows.

What's Down

Primary Impact: JWT token validation and authentication

Affected Services: REST API endpoints, PostgREST, real-time subscriptions

User Impact: Requests with valid tokens are being rejected with 401 Unauthorized responses

Scope: Appears to be affecting multiple projects; I'm unable to confirm if this is region-specific without current status page data

How to Check If You're Affected

1. Check Supabase Status Page: https://status.supabase.com/ 2. Test Your Connection: ```bash curl -H "Authorization: Bearer YOUR_JWT" \ https://YOUR_PROJECT.supabase.co/rest/v1/ ``` 3. Monitor Console: Check browser dev tools for 401 responses in network tab 4. Application Logs: Review server logs for JWT rejection errors

Immediate Workarounds

Temporary Solution 1: Token Refresh

Force logout and re-authenticate all users

Clear browser localStorage/sessionStorage

Regenerate JWT tokens from your auth provider

Temporary Solution 2: Direct Database Connection

If you have direct PostgreSQL access: ```bash psql postgresql://postgres:PASSWORD@db.YOUR_PROJECT.supabase.co:5432/postgres ``` Note: I'm unsure if this avoids the JWT layer or if it's affected.

Temporary Solution 3: API Key Authentication (if applicable)

Test using service role keys instead of user JWTs: ```bash curl -H "Authorization: Bearer YOUR_SERVICE_ROLE_KEY" \ https://YOUR_PROJECT.supabase.co/rest/v1/ ```

Alternative Services During Outage

Firebase/Google Cloud: Alternative auth provider with real-time database

AWS Cognito + RDS: Similar architecture for authentication + database

Hasura: GraphQL alternative with authentication layers

PlanetScale: MySQL alternative for data access

Rollback Steps

1. Check Supabase dashboard for recent deployments 2. Review your project's auth configuration for recent changes 3. If you modified JWT secret recently, verify the change propagated correctly 4. Clear CloudFlare cache if using CDN (Settings > Cache > Purge Everything)

What We Don't Know

Root Cause: Unable to confirm if this is infrastructure, configuration, or code-related

ETA: No confirmed timeline for resolution

Affected Regions: Unclear if this is global or region-specific

User-Specific vs. Service-Wide: Unable to confirm scope definitively

Recommendations

1. Immediate: Check Supabase status page and their official channels 2. Short-term: Implement token refresh logic in your client 3. Long-term: Consider multi-auth redundancy for critical applications 4. Monitor: Subscribe to Supabase status updates
