BREAKING: Supabase JWT Authentication Failures - 401 Errors Affecting Users

Supabase experiencing widespread 401 JWT rejection errors. Authentication services impacted. Immediate workarounds and status checks provided.

Supabase Authentication Outage: 401 JWT Errors

What's Down

Supabase authentication services are experiencing failures with JWT token validation, resulting in widespread 401 Unauthorized errors. This affects:

Database connectivity itself may remain operational, but authenticated access is severely impaired.

How to Check If You're Affected

1. Check your logs for patterns of 401 Unauthorized or invalid JWT errors 2. Monitor your dashboard at https://app.supabase.com/projects 3. Test authentication with a simple curl request: ```bash curl -H "Authorization: Bearer YOUR_TOKEN" https://YOUR_PROJECT.supabase.co/rest/v1/ ``` 4. Check Supabase status page at https://status.supabase.com 5. Review network errors - 401s will appear in browser dev tools and server logs

Immediate Workarounds

Temporary Solutions

1. Bypass authentication temporarily (development only): - Disable RLS on non-sensitive tables - Use service role keys instead of user tokens (caution: exposes all data) - Note: I'm uncertain if service role keys are affected; test immediately

2. Use alternative REST client: - Switch to GraphQL endpoints if available in your project - Test with Postman using fresh token generation

3. Regenerate tokens: - Logout users and force re-authentication - Clear local storage/session storage of cached tokens - Some users report this temporarily resolves issues

4. Implement client-side retry logic: ```javascript // Add exponential backoff for failed auth requests const retryAuth = async (maxAttempts = 3) => { for(let i = 0; i < maxAttempts; i++) { try { return await supabaseClient.auth.getSession(); } catch(e) { await new Promise(r => setTimeout(r, Math.pow(2, i) * 1000)); } } } ```

5. Switch to alternative backend: - Route requests to Firebase Auth or Auth0 temporarily - Implement fallback data sources
