Worried about a family member making unauthorized purchases? Maybe you don't want your children playing rated M games? You're not alone. A quick way to mitigate this is to set up a system restrictions passcode on PS4. This is different from two-factor authentication and prevents anyone from tampering with the parental control settings. And when you want to keep someone out of your account, you can set up a quick login passcode so that only you can login to the family manager's local user.
Select either Change Passcode or Delete Passcode.

Now, when you want to keep your entire account and personal information as secure as possible, that's when you'll want to set up two-factor authentication on your PlayStation 4.

Keep people from using your credit card
