Looking to safeguard itself against future breaches, breach suits, and having to give out free stuff, Sony has included an additional layer of security for PlayStation Network accounts in two-factor verification.
The security measure is just like it sounds: it offers another layer of protection to account so that you’ll need something like secondary password, pin number, or so in addition to your primary credentials. In online security communities, two-factor verification is widely suggested for social networks and personal email accounts.
PlayStation 4 users can set it by going to settings, Network Account Management, Account Information, Security, and finally 2-Step Verification. It’s also possible to set it up online through the Security option under your account.
If you’re on PlayStation 3, PSP, and/or Vita you’ll have to go with generating a device setup password or coming up with something so random and complex you have to keep it stored somewhere.
