Supabase Auth
Built-in authentication system with social providers, PostgreSQL policies, and user management. No external services needed - own your data completely.
Complete authentication solution that comes built into every Supabase project, eliminating the need for external authentication services. Handle user management, social logins, and access control all in one place.
Social login integration supports major providers including Google, Facebook, GitHub, Azure, GitLab, Twitter, and Discord - enabled with just a click. No complex setup or third-party dependencies required.
PostgreSQL-powered security uses Row Level Security policies for fine-grained access control. Write authorization rules directly in SQL or through the visual dashboard, controlling exactly who can create, edit, and delete specific database rows.
Data ownership guaranteed - all user data stays in your Supabase database across 16 global locations. Never worry about third-party privacy issues or vendor lock-in with your sensitive user information.
Simple, powerful APIs work seamlessly on both client and server-side applications. Handle sign-up, sign-in, magic links, and OAuth flows with straightforward, well-documented endpoints that developers actually understand.
