Single Sign-On (SSO)

The Hugging Face Hub gives you the ability to implement mandatory Single Sign-On (SSO) for your organization.

We support both SAML 2.0 and OpenID Connect (OIDC) protocols.

This feature is part of the Enterprise Hub. For enhanced capabilities like automated user provisioning (JIT/SCIM) and global SSO enforcement, see our Advanced SSO documentation

##
How does it work?

When Single Sign-On is enabled, the members of your organization must authenticate through your Identity Provider (IdP) to access any content under the organization’s namespace. Public content will still be available to users who are not members of the organization.

We use email addresses to identify SSO users. Make sure that your organizational email address (e.g. your company email) has been added to your user account.

When users log in, they will be prompted to complete the Single Sign-On authentication flow with a banner similar to the following:

Single Sign-On only applies to your organization. Members may belong to other organizations on Hugging Face.

We support role mapping and resource group mapping. Based on attributes provided by your Identity Provider, you can dynamically assign roles to organization members, or give them access to resource groups defined in your organization.

###
Supported Identity Providers

You can easily integrate Hugging Face Hub with a variety of Identity Providers, such as Okta, OneLogin or Azure Active Directory (Azure AD). Hugging Face Hub can work with any OIDC-compliant or SAML Identity Provider.

How to configure OIDC/SAML provider in the Hub

We have some guides available to help with configuring based on your chosen SSO provider, or to take inspiration from:

###
Users Management

####
Session Timeout

This value sets the duration of the session for members of your organization.

After this time, members will be prompted to re-authenticate with your Identity Provider to access the organization’s resources.

The default value is 7 days.

####
Role Mapping

When enabled, Role Mapping allows you to dynamically assign roles to organization members based on data provided by your Identity Provider.

This section allows you to define a mapping from your IdP’s user profile data from your IdP to the assigned role in Hugging Face.

- IdP Role Attribute Mapping

  A JSON path to an attribute in your user’s IdP profile data.

- Role Mapping

  A mapping from the IdP attribute value to the assigned role in the Hugging Face organization.

You must map at least one admin role.

If there is no match, a user will be assigned the default role for your organization. The default role can be customized in the `Members` section of the organization’s settings.

Role synchronization is performed on login.

####
Resource Group Mapping

When enabled, Resource Group Mapping allows you to dynamically assign members to resource groups in your organization, based on data provided by your Identity Provider.

- IdP Attribute Path

  A JSON path to an attribute in your user’s IdP profile data.

- Resource Group Mapping

  A mapping from the IdP attribute value to a resource group in your Hugging Face organization.

If there is no match, the user will not be assigned to any resource group.

####
Matching email domains

When enabled, Matching email domains only allow organization members to complete SSO if the email provided by your identity provider matches one of their emails on Hugging Face.

To add an email domain, fill out the ‘Matching email domains’ field, click enter on your keyboard, and save.

####
External Collaborators

This enables certain users within your organization to access resources without completing the Single Sign-On (SSO) flow described before. This can be helpful when you work with external parties who aren’t part of your organization’s Identity Provider (IdP) but require access to specific resources.

To add a user as an “External Collaborator” visit the `SSO/Users Management` section in your organization’s settings. Once added, these users won’t need to go through the SSO process.

However, they will still be subject to your organization’s access controls (Resource Groups). It’s crucial to manage their access carefully to maintain your organization’s data security.
