Supabase (Auth

A complete user management and authentication system built on PostgreSQL with support for social login, magic links, and Row Level Security.

Supabase Auth provides a production-ready authentication suite that integrates directly with your PostgreSQL database. It handles the heavy lifting of user management (signups, logins, and sessions) using JSON Web Tokens (JWTs) and supports over 20 social providers including Google, GitHub, and Apple. By leveraging PostgreSQL Row Level Security (RLS), you can define granular access control policies directly in your schema, ensuring that users only interact with the data they own. Whether you need enterprise-grade SSO (SAML), passwordless magic links, or multi-factor authentication (MFA), the system scales from local development to millions of users without requiring a separate authentication server.
