## Overview

- **Who it's for**: B2B SaaS teams that need to sell to enterprise buyers and must support IT-admin requirements like SAML/OIDC single sign-on and SCIM directory sync, without building and maintaining that plumbing in-house.
- **What you get**: AuthKit provides free hosted (or headless) sign-up/sign-in with email+password, social login, magic auth, and passkeys for up to 1M monthly active users, while paid per-connection APIs add Enterprise SSO, Directory Sync (SCIM), RBAC, and organization-scoped auth policies for B2B multi-tenant apps.
- **How it works**: You integrate WorkOS's SDKs (Node, Python, Go, Ruby, PHP, Java, .NET) or hosted AuthKit UI into your app, then configure each customer as an "organization" and "connection" in the WorkOS dashboard so their SAML/OIDC identity provider or SCIM directory syncs users, roles, and group membership into your product automatically.
