"Family Link," Google's parental controls for Android and Chromebooks, is growing up. Well, in a sense. For one, it's no longer limited to kids -- soon adults will also be able to manage their teen's devices with existing Google accounts. Wisely, that can only occur with the teenager's permission, and they can also "unlock" their devices after parental controls are enabled (though that'll send an alert to parents).
The idea isn't to control teens, instead it's a way for adults to still be involved as their kids grow more attached to devices. Parents won't be able to change teen's devices or change their passwords, like they can for younger children.
