Roblox also explained that it is phasing out the need for parents to set a parent PIN, receive account-related notifications to their parental email, or use Account Restrictions.

Finally, Roblox is introducing accounts with parent privileges. The current system is tied to parent’s email accounts and allow them to set a PIN and get notifications.

Prior to this, Roblox parental controls allowed parents to essentially set a PIN on a child's account that only the parent would know.
