Stytch

The platform provides a collection of APIs and SDKs that let developers integrate password‑less login, social sign‑in, and comprehensive user management into web and mobile applications. It supports a range of authentication methods, including passkeys, SMS, email, and device‑aware multifactor factors, and offers single‑sign‑on via SAML and OIDC. Backend features include role‑based access control, just‑in‑time provisioning, SCIM, and machine‑to‑machine authentication for service‑to‑service communication.

Developers can customize the login experience using pre‑built UI components or headless SDKs, while an embeddable admin portal lets enterprise customers self‑serve configuration, SSO setup, and organization settings. The service also includes bot and fraud protection with intelligent rate limiting and device intelligence, aiming to reduce login friction and improve security.

Designed for scalability, the system works from a single user to large enterprises, offering multi‑tenant data models, fine‑grained API access, and turn‑key features such as cross‑application integrations and AI‑agent support. It is positioned as a stable, enterprise‑grade authentication solution for teams building applications that require secure, frictionless identity management.
