You can get started with system or PlayStation Network features quickly and take advantage of remote download if auto sign in is set up.
However, this means that your account may be easily accessed by others who can use your PlayStation system. Therefore, there are certain situations where you should not have auto sign-in enabled.
There are two accounts that you can sign in to on your PlayStation 3; the local user account, which is the user on the PlayStation system itself and the PlayStation Network account, which can be linked to local user accounts on different activated systems for playing online, making purchases from PlayStation Store etc.
Local user accounts do not have any password or PIN settings. If there is only one local user or, if [Automatic Login] is enabled on one of the local user accounts, the PlayStation 3 will automatically log in to this user when it is switched on.
To switch off auto log-in go to [PlayStation Network] with your [Local user] and press (Triangle button). Select ‘Automatic Login’ and press (X button).
However, this does not stop others from manually choosing to log into the PlayStation 3 on your local user account.
The PlayStation Network account assigned to the local user account cannot be changed after it has been chosen. Your local user account does not stay signed in to PlayStation Network but you can set up automatic sign in on your local user. You can also save your password to sign in quickly if you do not want the PlayStation 3 to sign in to your account automatically.
If these settings are switched on, it means that because any user can access to your local user account, they can also access your PlayStation Network account information and any content purchased by any other local user on the PlayStation 3.
Sign out of PlayStation Network at the end of every PlayStation 3 session and make sure [Auto Sign-In] is switched off to stop others accessing your account by going to [PlayStation Network] > [Account Management] and pressing (triangle button).
If you have saved your password other users can access your PlayStation Network account, even if you have signed out and switched off [Auto Sign-In]. Make sure your password has not been saved by doing the following:
Go to [PlayStation Network] > [Sign In] and if the check box next to [Save Password] is ticked, highlight it and press (X button) to untick.
You should sign out at the end of every session on your PlayStation 3, but be extra careful if any of the following apply:
If you do not have access to your PlayStation system to sign out of PlayStation Network, you can you can change your password from a web browser. This means that if another person has possession of your PlayStation system they cannot access your account through it, even if auto sign-in or saved password is switched on.
