Multi-Tenant Auth with Supabase

Secure, production-ready multi-tenant authentication starter template

🔐 Security-First Architecture

  • ✓Backend-controlled email generation - No client-side hashing
  • ✓Webhook signature verification - HMAC-SHA256 validation
  • ✓Rate limiting - Protection against brute force attacks
  • ✓Email enumeration protection - Consistent responses
  • ✓True tenant isolation - Same email, different tenants

🚀 Try the Demo

Test multi-tenant authentication by signing up with the same email on different tenants:

Tenant A

Sign up or log in to Tenant A

Try it →

Tenant B

Sign up or log in to Tenant B

Try it →

Test it: Use the same email (e.g., test@example.com) on both tenants with different passwords. Both accounts will work independently!
