New and existing users under the age of 18 will be automatically enrolled in what Instagram is calling "Teen Accounts," the company said. The move comes 16 months after U.S. Surge

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.

Starting today, Instagram will begin putting new and existing users under the age of 18 into “Teen Accounts” — a move that will affect how tens of millions of teens interact with the platform. The new account type automatically applies a set of protections to young users, and only users 16 years of age and older can loosen some of these settings.
