Roblox will scan video selfies of teens to assess their ages as part of a new Trusted Connections feature that gives users access to unfiltered chatting with people they know.

Roblox is joining the growing ranks of online platforms that are trying to better understand the ages of their teen users. The company is rolling out a new "age estimation" feature for teens 13 and older.

Now teens ages 13 to 17 who want to access a special feature designed to make those hangouts even more fun will have to verify their age via a video selfie. Roblox announced the new requirement Thursday as part of a slate of safety and privacy measures.
