Add an option where you can disable logging out of a chromebook
At my school we do not allow personal accounts on chromebooks only school accounts, however, students are getting around filters by logging into their personal accounts.
As a chrome extension, we don’t have this ability.
That said, Google Admins (IT administrators) can set a setting in the Google Admin Console to take care of this!

Students are able to login as guest as well...

This can be done through enterprise management of the chromebook.
