Roblox Corp. is adding new safety features, including an age-estimation tool that relies on video selfies, in an effort to better protect its kid-heavy user base.

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.

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.
