Roblox is making two big changes to its wildly popular online gaming platform used by millions of children globally. The San Mateo-headquartered tech company has been criticized by some parents for lacking online security safeguards.

Roblox announced Thursday that it’s launching new safeguards for people who are between the ages of 13 and 18. The company is introducing “Trusted Connections” to allows these users to connect more freely with people they know, alongside age estimation technology, more privacy tools, and insights for parents of teens.

Following accusations of grooming and predatory behavior experienced by its younger-skewing users, Roblox rolled out new safety features Thursday.
