Open the main Settings menu on your PlayStation 4 or PlayStation 5, and then select “Users and Accounts.” That should bring up a sub-menu with further options; you want the one that says “Account” (it should be the top option).
Log in to your PlayStation Network account. Select Users and Accounts from the Settings menu. Select Account, then Security, and then 2-Step Verification from the drop-down menu. Select Activate. Then you must choose between Text Message and Authenticator App. You’ll need to provide your mobile phone number for Text Message. A verification code will be sent to you through text. Download and install an authenticator app on your mobile device for authentication. Scanning the QR code on the screen will open the app. The program will then prompt you for a verification code. Make a note of your Backup Codes and the verification code you got.
The setup process for PlayStation 2SV in your browser is essentially the same as it is on the console, although the methods to get there varies slightly. The advantages of two-factor authentication are self-evident: it makes your PS5 and PS4 PSN accounts significantly more secure. All that is required to enter into your PSN account without 2FA is your username and password. While this is usually acceptable, it does mean that if someone gets their hands on your login information, they’ll be able to get in with ease.
