What is Stytch?
Stytch is an authentication and fraud prevention platform for B2B and consumer applications. It is made by Stytch and provides APIs, SDKs and prebuilt UI for sign-in, sessions, organization management, single sign-on and machine-to-machine access. The problem it solves is auth complexity at scale: teams get multi-tenancy, SSO, SCIM and role controls without building each flow and security policy themselves.
Key features
- Passwordless and password auth. Email magic links, one-time codes, OAuth, passkeys and passwords can be combined in one project.
- B2B organization management. Organizations, member invitations, roles, metadata and organization-level auth policies are built in.
- SSO and SCIM. SAML and OIDC connections, SCIM provisioning and just-in-time provisioning are available without a separate identity product.
- Sessions and authorization. Session management and role-based access control cover both people and machine-to-machine tokens.
- Fraud and risk tools. Optional CAPTCHA, bot detection, device fingerprinting, rate limiting and custom authorization verdicts add protection.
- Prebuilt UI. Login and admin portal components reduce the front-end work for common auth screens.
- Flexible deployment. Hosted APIs cover most teams, while enterprise plans add custom support and a 99.99% uptime SLA.
Who is Stytch for?
B2B SaaS companies that need SSO, SCIM and organization-level permissions, and consumer apps that want passwordless sign-in. It suits product teams that want auth APIs with prebuilt UI instead of a fully hosted identity suite, and platforms that need both human users and machine-to-machine tokens. It is also used by companies that want fraud signals next to authentication rather than in a separate tool.
Use cases
- Adding Google and Microsoft SSO for enterprise customers.
- Letting users sign in with passkeys or email magic links.
- Managing organizations, roles and member invitations in a B2B product.
- Issuing machine-to-machine tokens for service-to-service calls.
- Adding bot detection and device fingerprinting to a sign-up flow.
