Does Google Family Link work on Chromebook?

Yes, Google Family Link works on Chromebooks. Family Link supervision can be enabled on Chromebooks running Chrome OS version 71 or higher.

However, a known limitation mentioned in user discussions is that Family Link might not prevent a child from logging into Guest mode, which bypasses parental controls unless Guest browsing is explicitly disabled by the Chromebook owner account. Also, installing or using Linux on a Chromebook with a Family Link managed account is generally not allowed, as it could bypass Chrome OS restrictions.
