Manage single sign-on settings

Workspace owners and org owners can enable single sign-on (SSO) as an extra layer of security for their organisation. Depending on your Slack subscription, there are a few different settings that you can configure for your SSO setup.

Note: Learn how to set up SSO with SAML single sign-on and G Suite single sign-on

Tip: Workspace owners and org owners can bypass SSO authentication by using the link at the bottom of the sign-in page to sign in with an email address and password. This guarantees access to your workspace or org, even if your identity provider (IDP) is having issues.
