Meta has announced the global rollout of its "teen accounts" for users aged 13 to 17 on Facebook and Messenger, following a previous introduction in key English-speaking markets. Hundreds of millions of teens have been transitioned to these specialized accounts, which include enhanced security settings, content restrictions, and parental controls. The accounts feature built-in safeguards to limit interactions with strangers and control accessible content, while restrictions for users under 16 cannot be lifted without explicit parental consent. This initiative aims to address concerns about the impact of social media on young people.
