Remove single sign-on

If you’d like your team to go back to using Slack’s built-in authentication, or switch to a different identity provider (IDP), you can turn off single sign-on (SSO).

When SSO is turned off, team members will sign in using their email address and Slack password.


Turn off SSO

  1. Click your team name to open the Team Menu.
  2. Select Team Settings. This will open your team site.
  3. From the Authentication tab, click the orange button to Disable Google Auth or Switch to built-in authentication if you’re using SAML authentication.

    Team members will be sent an email to let them know about the change and to remind them to set a password, if they don’t already have one.✨


Switch to a different IDP

Once you’ve turned off your existing authentication method, you can switch and set up a new connection. Here are some helpful tips to consider:

Plan ahead

  • Plan to make the SSO changes within a short period of time.
  • Consider whitelisting the slack.com domain, so emails don’t get caught in your ISP's Spam or Junk mail folders. 
  • Make sure that the email addresses in Slack match with the primary email addresses in your IDP. This creates a more seamless experience for members the next time they need to authenticate, and connect their Slack account to your IDP.

Communicate the change

  • Let team members know about the changes and what to expect in advance by making a global announcement in your #general channel. Since you’re switching to a new IDP, let members know they can ignore the email that prompts them to create a password.

Reconnect team members

  • After you’ve set up the new authentication method, ask team members to click the SSO binding email within 72 hours. Administrators can always send a fresh binding email from the Team Members page.
