Parental controls on the PS4 are handled by having a Master Account (the standard PSN account) and linked Sub Accounts, that fall within the control and security of the Master Account. These Sub Accounts get their own PSN IDs, trophy lists, game purchases, etc. but the Master Account can control the funding of their PSN wallet and other monitoring of the Sub Account.
Everyone under 18 is supposed to have a Sub Account under a responsible adult’s Master Account (though let’s be real, we know that doesn’t always happen). Once those Sub Account holders turn 18 though, they probably want full control of their own account without losing their PSN ID, trophies, and library of games. This week’s Help Desk is going to show you how to upgrade a Sub Account to a full Master Account, but before we get into that, let’s understand the key differences between Sub and Master Accounts. Account Types
The following comparisons are directly from Sony on the differences between Sub and Master Accounts.
