Meta has added “Teen Accounts” to Facebook and Messenger to limit who can contact minors and screen the content they’re exposed to. On Tuesday, the tech giant announced that users under 18 will automatically be enrolled in these accounts in an attempt “to give parents more peace of mind across Meta apps” and curb exposure to inappropriate content.

The system imposes more restricted settings on younger users - though campaigners say it's unclear what difference they make.

Meta is bringing its “teen accounts” to Facebook and Messenger. Like on Instagram, the company will begin automatically moving younger teens to the new accounts, which come with mandatory parental control features and restrictions on who they can message and interact with.
