What you need to know

​
Configure Login with Google

Slack calls Login with Google “Google Workspace single sign-on”. They also sometimes refer to it as “Google Auth”.

We will configure Google as an authentication method and set it to enforce it to make sure people can only log in using Google.

We recommend you plan this change and notify your users how their experience will change and when the change will take effect
Tip: Workspace Owners and Org Owners can bypass SSO authentication by using the link at the bottom of the login page to sign in with email address and password. This guarantees access to your workspace or org, even if your IDP is having issues.

Setting NameEnabledExplanation
Update profile each time a user logs inYesEnable to make sure any profile changes in ShiftControl show up in Slack the next time the user authenticates.
Allow users to change their email addressNoAllowing users to change their own emails is dangerous, you should control the email they use to log in to Slack.
Allow users to change their display nameNoWe think it is cleaner to standardize display names, but this one is really up to you and your company culture!
Google auth must be used byAll Members, except guest accountsThis enforces Google authentication for everyone in your company. Guests are excluded because they usually don’t have Google Workspace accounts.

Click Save Configuration when you are done.

Authenticate to Google

You will be asked to authenticate with your Google account.

You do not need to authenticate with a Google Workspace Admin. Any user will work.
If the person that does this step is offboarded from the company (e.g., they no longer have a Google account), then another Slack Workspace Owner will need to come here and authenticate again to re-enable Login with Google.

Auth to Google

Congratulations, your Slack workspace is now set up for Login via Google!

​
How users are created

When a user goes to Slack for the first time, they will log in via Google and their account will automatically be created. No action is required for onboarding.
