## Authenticationbuilt in, not bolted on

Every Supabase project comes with a complete user management system. Including Postgres' Row Level Security for fine-grained access control.

### Everything you need  
for user authentication

Social logins, email/password, magic links, phone auth, and more — with enterprise-grade security built on Postgres' Row Level Security.

> Supabase is not only super easy to get started, but also provides all the backend solutions we require as we continue to grow. The auth system just works out of the box.
