Connect your SSO account to Slack

If a workspace owner enables single sign-on (SSO) or requires members to reauthenticate themselves, we’ll let you know. We’ll send you an email explaining how to connect (or “bind”) your Slack account with your identity provider (IdP).

Note: Your SSO binding email will expire after 72 hours. You can always request a new email from a workspace owner or admin.

Click the Authenticate your account button in the binding email to get started. The process takes less than a minute!


Note: You can connect your SSO account to Slack from your desktop or mobile device.

Rebind your SSO account after a session reset

If they want to, workspace owners can initiate an SSO session reset. If that happens, members will be signed out of Slack and receive an SSO rebinding email.

To sign back into your workspace, complete the steps below to reconnect your Slack account to your IdP. You’ll then be able to sign in using your IdP.

  1. To rebind, click the Sign in to authenticate your account button in the binding email.
  2. Users may see an option to Remain associated with their account (continue using the same account they had been using) or Switch.

Tip: To retain your message history in Slack, make sure that you choose the option to remain associated with your account.
