If you are like most people, you probably have a PlayStation 4. But if you’re like me, you may be wondering how to deactivate your PlayStation 4 as your primary system without losing data. The easiest way to do this is to use the PlayStation 4’s built-in security feature. To do this, open the console’s Settings and select Security. Under the “Security” tab, select “Deactivate PS4 as primary system.” This will take care of activating your PlayStation 4 as your primary system and disabling any other systems that are connected to it.
