The Auth0 Tax
Auth0 charges per MAU. At scale, you are paying $0.05-0.23 per user per month just for login. For a platform serving 20+ products, that is a six-figure line item.
What We Built Instead
Auth1 is a multi-tenant auth platform: SMS OTP (Twilio + SNS failover), magic links, social login, session management, per-tenant branding, Stripe billing. Each tenant gets one API key.
You do not need separate databases per tenant. You need separate trust boundaries. Auth1 uses row-level tenant isolation in PostgreSQL with API-key-scoped queries. One database, 20+ tenants, zero cross-tenant data leaks.
Auth1 — multi-tenant auth, PQ-secured, zero vendor lock-in.
Introducing H33-74. 74 bytes. Any computation. Post-quantum attested. Forever.
