There are a few ways to remove someone from your family on PlayStation 4. One way is to use the PlayStation 4’s built-in removal tool. Another way is to use the console’s online mode. The third way is to use a game controller.
Log into your PS4 account via the PlayStation Network website or through the PlayStation App. Select “Ps4” in the upper right corner of the screen. Select “PlayStation Network/Account Management” in the left column of options, and then select “Manage Family Members” in the column on the right.
