## What it is
Authorizer is an open-source, self-hosted authentication and authorization server written in Go, providing OAuth2/OIDC, SAML SSO, MFA, social logins, magic links, passkeys, and fine-grained ReBAC authorization via an embedded OpenFGA engine. It supports 13+ database backends so user data stays in your own database, and ships with a built-in login page, admin dashboard, and an MCP server for permission-aware AI agents.

## Use cases
- self-host user authentication instead of Auth0 or Clerk
- add OAuth2 and OIDC login to my app
- implement role-based access control with my own database
- add social logins and magic link passwordless sign-in
- set up enterprise SSO with SAML and SCIM provisioning
- check user permissions from an AI agent before RAG retrieval
- add multi-factor authentication with TOTP and passkeys

## When to choose
- you want full control over user data and identity infrastructure in your own cloud or VPC
- you need OAuth2/OIDC, SAML, MFA, and fine-grained authorization from a single self-hosted service
- you want to keep user records in an existing database like Postgres, MySQL, or MongoDB
- you need permission-aware AI agents via a built-in MCP server

## When to avoid
- you prefer a fully managed hosted identity provider with no operational burden
- you need only a lightweight embedded auth library inside a single app rather than a standalone server
- you cannot operate a stateful service with database, secrets, and key rotation responsibilities
