SAML authentication
This feature is only available to organization owners and administrators.
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.
Zulip Cloud customers who wish to use this feature must upgrade to
the Zulip Cloud Plus plan.
