About SAML single sign-on

You can enable SAML SSO in your organization without requiring all members to use it. Enabling but not enforcing SAML SSO in your organization can help smooth your organization's SAML SSO adoption. Once a majority of your organization's members use SAML SSO, you can enforce it within your organization.

Note: To use SAML single sign-on, your organization must use GitHub Enterprise Cloud. For more information about how you can try GitHub Enterprise Cloud for free, see "Setting up a trial of GitHub Enterprise Cloud."

If you enable but don't enforce SAML SSO, organization members who choose not to use SAML SSO can still be members of the organization. For more information on enforcing SAML SSO, see "Enforcing SAML single sign-on for your organization."

Note: SAML authentication is not required for outside collaborators. For more information about outside collaborators, see "Roles in an organization."

When SAML SSO is disabled, all linked external identities are removed from GitHub Enterprise Cloud.

After you enable SAML SSO, OAuth app and GitHub App authorizations may need to be revoked and reauthorized before they can access the organization. For more information, see "Authorizing OAuth apps."

Enabling and testing SAML single sign-on for your organization

Before your enforce SAML SSO in your organization, ensure that you've prepared the organization. For more information, see "Preparing to enforce SAML single sign-on in your organization."

For more information about the identity providers (IdPs) that GitHub supports for SAML SSO, see "Connecting your identity provider to your organization."
