Hmm...we can't find this setting yet, but we'll keep checking. Feel free to contact us for help.
Looks like you're signed in with a Gmail account. Please try again with your account that you use to access Google Admin.
Setting the policy turns on Chrome's restricted sign-in feature in Google Workspace and prevents users from changing this setting. Users can only access Google tools using accounts from the specified domains (to allow gmail or googlemail accounts, add consumer_accounts to the list of domains). This setting prevents users from signing in and adding a Secondary Account on a managed device that requires Google authentication, if that account doesn't belong to one of the explicitly allowed domains.
Leaving this setting empty or unset means users can access Google Workspace with any account.
Users cannot change or override this setting.
Note: This policy causes the X-GoogApps-Allowed-Domains header to be appended to all HTTP and HTTPS requests to all google.com domains, as described in https://support.google.com/a/answer/1668854.
