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.
