Perhaps too little, too late but it’s still a welcome addition, nonetheless. Sony PlayStation Network users can now enable two-factor authentication for your accounts. You can get full details about how to activate the feature here. Those who opt to do so (which we highly recommend you do) will receive codes via SMS that you need to input alongside your password and username before you can sign in. While two-factor authentication might not be hack-proof, it’s still an added security that we welcome.
