SAML authentication

{!admin-only.md!}

Zulip supports using SAML authentication for single sign-on, both for Zulip Cloud and self-hosted Zulip servers. SAML Single Logout is also supported.

This page describes how to configure SAML authentication with several common providers:

  • Okta
  • OneLogin
  • AzureAD
  • Keycloak
  • Auth0

Other SAML providers are supported as well.

If you are self-hosting Zulip, please follow the detailed setup instructions in the SAML configuration for self-hosting. The documentation on this page may be a useful reference for how to set up specific SAML providers.
