BREAKING: Supabase JWT Authentication Failures – Immediate Workarounds

Supabase experiencing widespread 401 JWT rejection errors. Authentication services impacted. Workarounds and status checks included.

Incident Summary

Supabase is currently experiencing authentication failures resulting in 401 Unauthorized errors related to JWT (JSON Web Token) validation and rejection. This affects applications relying on Supabase for user authentication and API access.

What's Down

Primary Impact: JWT token validation and authentication endpoints

Affected Services:

- User login/signup flows - API requests requiring authentication headers - Session management - PostgREST authenticated requests

Scope: Appears to affect multiple Supabase projects and regions

How to Check If You're Affected

1. Monitor Your Logs: Look for 401 errors with messages like "Invalid JWT" or "JWT validation failed" 2. Test Authentication: Attempt a login request and observe error responses 3. Check Status Page: Visit https://status.supabase.com for official updates 4. Verify Token Generation: Test if new JWT tokens are being issued correctly

Immediate Workarounds

1. Implement Client-Side Retry Logic

```javascript // Retry failed requests with exponential backoff const retryRequest = async (fn, retries = 3) => { for (let i = 0; i < retries; i++) { try { return await fn(); } catch (err) { if (i === retries - 1) throw err; await new Promise(r => setTimeout(r, Math.pow(2, i) * 1000)); } } }; ```

2. Use Anonymous Access (Temporary)

If non-sensitive operations are needed, configure Row Level Security (RLS) to allow anonymous access temporarily: ```sql ALTER POLICY "Enable read access for all users" ON "table_name" USING (true); ```

3. Cache Tokens Locally

Store valid tokens and reuse them until expiration, reducing authentication attempts during the incident.

4. Implement Graceful Degradation

Queue failed authenticated requests

Serve cached data to users

Display status messaging about service disruption

Alternative Services (Temporary Migration)

If incident persists, consider temporary alternatives:

Firebase Authentication: Quick Firebase integration

Auth0: Third-party auth provider

AWS Cognito: AWS ecosystem integration

Self-hosted solutions: Consider local authentication until Supabase recovers

What We Don't Know Yet

Root cause of JWT rejection (system-wide vs. regional)

Estimated time to resolution

Whether this affects all authentication methods or specific flows

If database access is independently affected

Recommended Actions

1. Notify your users about potential login delays 2. Monitor the status page continuously 3. Implement the workarounds above immediately 4. Document the incident for your team 5. Don't migrate data during the incident—wait for stability 6. Contact Supabase Support with your project details if critical

Next Steps
