Stytch Authentication and Authorization
Auth ready for what comes next
The leading identity platform for user and AI agent authentication, authorization, and security. Stytch offers all the flexibility of in-house auth without the engineering burden as you scale.
Leave your auth roadmap to us
Skip the middleware
Build with auth that's native to your stack—consumer, B2B, or hybrid. No glue code. No workarounds.
When users are individuals (people and AI agents) and you need frictionless sign‑in at scale (passkeys, email/OTP, social), plus reliable recovery and device continuity.
Stytch for consumer apps
Enterprise features
SSO, SCIM directory sync, RBAC, MFA with provider failover, audit logs, and 99.99% uptime SLA— all out of the box.
Scale without rewrites
Identity stitching, multitenancy, and self-serve admin tools let you onboard thousands without re-architecting.
Unmatched flexibility
Drop-in frontend SDKs to ship faster. Headless SDKs and backend APIs with per-tenant workflows when you need full control.
Easily extend auth to AI agents, MCP, and 3rd-party applications with Connected Apps
Third-party data sharing
Let partner apps fetch scoped user data without building custom auth flows.
AI agents & delegated access
Enable agentic workflows that can perform programmatic, permissioned actions on behalf of users.
Secure session sharing
Enable cross-device and cross-domain sign-on for a more seamless and secure user experience for use cases like IoT and multi-branded orgs.
App marketplace & plug-ins
One-click installs and “Sign in with your-app” flows to easily build bots and apps in external ecosystems.
Authentication and authorization supercharged with device intelligence
The most advanced fraud and abuse prevention built-in. Protecting your users and application by unlocking powerful authentication features.
Fingerprint protected auth
SDK that protects your application from account takeover (ATO) and related attacks by implementing a Device Fingerprinting check on every authentication request.
Better OTP & 2FA checks
Remove login friction for your users by only requiring multi-factor authentication when your they log in from unrecognized devices.
Better than CAPTCHA
Don't make your users click on stop signs. Invisible bot detection improves UX and conversion by only adding friction to suspicious traffic.
Smart magic links
Reliable delivery of email magic links that work with and pass enterprise-level security link checkers.
What engineering teams are saying
We knew we needed to upgrade our in-house auth, and that would be a big undertaking. Having a partner who was thinking through these problems for us and could allow us to be more lean with what we were maintaining was a lot of the motivation in moving to Stytch.
