SSO Migration Gateway (beta) for fast, disruption-free migration to Stytch SSO 

Stytch’s new SSO Migration Gateway makes it possible to migrate your SSO implementation to Stytch without disrupting existing login flows. The migration gateway acts as a reverse proxy that routes SAML callbacks between your existing auth service and Stytch with no user-visible changes. Just point your login domain at the gateway via DNS, and we handle first-pass to Stytch with automatic failover to the legacy provider if needed. The result: incremental, low-risk cutover to Stytch enterprise SSO without app rewrites or downtime.

How it works

• The gateway receives SAML callbacks and intelligently routes them to either Stytch or your legacy auth provider after inspecting the request.  These routing decisions are logged so you can monitor behavior during migration.

• Our gateway callback handler derives the target connection from the SAML Issuer (and optional RelayState), so you don’t need connection ID-specific callback URLs.

• In the Stytch dashboard, enable connections individually with “Allow gateway processing” to pilot, ramp, and roll back as needed.

Getting started

Let us know if you’d like access to the beta. We’ll provision a gateway and validate the setup, then you can update your DNS to route traffic through it. From there, you can start migrating connections at your own pace.

To get beta access, contact the Stytch team.
