Roblox is employing technology from Persona, a San Francisco identification verification company whose website says it can “Ensure that users are who they say they are.” However, Roblox will not use Persona to identify the actual identity of the user, just an estimate of their age, according to Roblox VP of Civility and Partnerships Tami Bhaumik.

In addition to confirming ages for individual accounts, Roblox also said it plans to adopt new systems that will limit communication between adults and minors unless they already know each other offline.
