+# Advanced Single Sign-On (SSO)
+
+<Tip warning={true}>
+This feature is part of the <a href="https://huggingface.co/contact/sales?from=enterprise" target="_blank">Enterprise Plus</a> plan.
+</Tip>
+
+Advanced Single Sign-On (SSO) capabilities extend the standard [SSO features](./security-sso) available in the Enterprise Hub, offering enhanced control and automation for user management and access across the entire Hugging Face platform for your organization members.
+
+## User Provisioning
+
+Advanced SSO introduces automated user provisioning, which simplifies the onboarding and offboarding of users.
+
+*   **Just-In-Time (JIT) Provisioning**: When a user from your organization attempts to log in to Hugging Face for the first time via SSO, an account can be automatically created for them if one doesn't already exist. Their profile information and role mappings can be populated based on attributes from your IdP.
+*   **System for Cross-domain Identity Management (SCIM)**: For more robust user lifecycle management, SCIM allows your IdP to communicate user identity information to Hugging Face. This enables automatic creation, updates (e.g., name changes, role changes), and deactivation of user accounts on Hugging Face as changes occur in your IdP. This ensures that user access is always up-to-date with their status in your organization.
+
+## Global SSO Enforcement 
+
+Beyond gating access to specific organizational content, Advanced SSO can be configured to make your IdP the mandatory authentication route for all your organization's members interacting with any part of the Hugging Face platform. Your organization's members will be required to authenticate via your IdP for all Hugging Face services, not just when accessing private or organizational repositories.
+
+This feature is particularly beneficial for organizations requiring a higher degree of control, security, and automation in managing their users on Hugging Face.

 Single sign-on (SSO) allows organizations to securely manage user authentication through their own identity provider (IdP). Both SAML 2.0 and OpenID Connect (OIDC) protocols are supported.
 
+Please note that this feature is intended to manage access to organization-specific resources such as private models, datasets, and Spaces. However, it does not replace the core authentication mechanism for the Hugging Face platform.
