Roblox is widening its age-check system as it prepares to introduce two age-specific accounts. The gaming company is defending the changes after parents raised concerns about errors in the checks.

The move is part of a wider update to its technology. Roblox said it is extending the system to create accounts based on age.

Roblox has 144 million daily users. The company is one of the largest gaming platforms and its age checks have drawn close attention from parents.
