What is the local account and how does it differ from my PLAYSTATION®Network account?Answer
Your local account is the user account for the PS3 system, and is accessed any time you play on the PS3 system whether or not you access the PLAYSTATION®Network. Your PLAYSTATION®Network account is the account you use anytime you are on the PLAYSTATION®Network. If you do not want to access the PLAYSTATION®Network, you do not need a PLAYSTATION®Network account. However, you must have a user account in order to have a PLAYSTATION®Network. The PLAYSTATION®Network account must be bound to a user account.
