You can get started with system or PlayStation Network features quickly and take advantage of remote queuing.
However, this means that your account may be easily accessed by others who have access to 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 PS TV; 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.
You can only assign one local user account to your PS TV at any one time. This means that the PS TV will automatically log in to this user when it is switched on. Auto log-in to local user cannot be switched off.
The PlayStation Network account assigned to the local user account cannot be changed after it has been chosen. Once your local user account is signed in to PlayStation Network, it stays signed-in in the background and automatically signs back in when you switch on your PS TV, even if the system was switched off completely.
This means that any user with access to your PS TV can also access your PlayStation Network account information.
Sign out of PlayStation Network at the end of every PS TV session to stop others accessing your account by going to [Settings] > [PlayStation Network] > [Sign Out].
