Teens have long ruled the internet, but internet safety for teens is all the rage right now. YouTube, Spotify, and Snapchat have all recently introduced parental controls. Uber has an entire “Uber for Teens” campaign with grim ads about kids getting kicked off the soccer team and texting their parents on the way home. Now Instagram has introduced mandatory “teen accounts” that have privacy built in.

Starting Tuesday, new users under 18 will automatically receive a Teen account, while teens who already have an account will be transitioned over the next 60 days. The new settings will automatically make Teen accounts private instead of public; users under 16 will need a parent’s permission to transition to public accounts. Teen accounts will only let users message people they follow, and there will be a setting that allows parents to see who their teens are messaging. Teens will be able to choose “age-appropriate” topics for posts fed to them by the algorithm (which their parents can also see), and all Teen accounts will be put into “sleep mode,” which limits users’ access to the app from 10 p.m. to 7 a.m.

Instagram’s Adam Mosseri announced Teen Accounts on Good morning America on Tuesday and said the new setting was an attempt “to proactively address the top concerns we’ve heard from parents about their teens’ online activity… things like who can contact them, what content they’re seeing, and how much time they’re spending on their device… all without requiring parental intervention.”

In the past, it would have been easy for a teenager to lie about their birthday and get around such a restriction, but Meta (which owns Instagram) is working on technology “designed to identify age liars,” according to vice president and global head of security Antigone Davis. Teens must confirm their age when they try to change their account’s birth date, and accounts with different birthdays on the same device will be locked.

Will these changes really address concerns about the mental health impact of social media on teens? Or will teens instead simply find new apps with fewer protections? It will be interesting to see if this is a real turning point for internet safety or if these new settings are just a band-aid on a bullet hole.
