WorkOS

WorkOS is a hosted platform that gives an application authentication, single sign-on, user management and authorization through its APIs. Its single sign-on speaks SAML and OpenID Connect, and the documentation describes RESTful endpoints that return JSON. The homepage lists further products beyond sign-in, among them directory sync, role-based access control, multi-factor authentication, an admin portal for corporate IT administrators, and fine-grained authorization. Migration guides cover moving users over from other authentication services.

Worth knowing

The service runs on the vendor’s infrastructure, and the pages read name no way to install or run it yourself. The pricing page includes a free allowance of active users before paid plans, and its enterprise plan includes single sign-on.
