You can restrict the use of Chrome to only the accounts you want to use it by enforcing a few group policies. The most recent of these is to force users to sign into Chrome. However, this policy need others to make it effective. Below are the ones I use. Update - see this page for the latest policies that replace the first two listed below. Firstly - force users to sign in to Chrome Make sure they can only use a domain account Make sure they cannot use accounts you don't want them using in G Suite services Disable incognito mode Disable guest mode Disable add user (might not want to use this for a staff account as they may need to use more than one account) With this combination of policies, your users are locked down to their G Suite account and cannot do anything about it.
