So I tore it to pieces today.  I was using Google FamilyLink to manage my teen's computer use, but with two factor authentication and other needs, parental controls made it unworkable for him to use it.  I deleted my FamilyLink group and removed my child, but then I couldn't log in to the child's Chromebook anymore without the FamilyLink permission.  So now it is gone.  It wouldn't allow restore to factory settings or anything else, all was blocked by FamilyLink password.
