# Single Sign-On

Single sign-on (SSO) is a property of identity and access management (IAM) that enables users to securely authenticate with multiple applications by logging in only once (with just one set of credentials). For SSO, Seldon Enterprise Platform relies on the OIDC protocol that handles authentication through JSON Web Tokens and a central identity provider to verify user identity.

A typical enterprise SSO flow for web based applications is as follows

As shown in the diagram, Seldon Enterprise Platform sso integration works if any enterprise application on `domain1.com` and a Seldon Enterprise Platform installation on `domain2.com` is connected to a common auth Server on `domain3.com`.

Currently, Seldon Enterprise Platform SSO can be configured in [two ways](/seldon-enterprise-platform/architecture/authentication.md).
