Meta has announced new Instagram Teen Accounts. But what exactly are they? How will affect my teen's account? Here's what you need to know.

Beginning Tuesday in the U.S., U.K., Canada and Australia, anyone under under 18 who signs up for Instagram will be placed into a teen account and those with existing accounts will be migrated over the next 60 days. Teens in the European Union will see their accounts adjusted later this year.

Instagram is making teen accounts private by default as it tries to make the platform safer for children amid a growing backlash against how social media affects young people’s lives.
