While you are a PlayStation®Plus subscriber, other people using your PS3 system or PS4 system can access selected PlayStation®Plus membership benefits from your system.
You can also access your PlayStation®Plus membership benefits on other people’s PS3 system or PS4 systems.
PlayStation®Vita allows only one user at any time. Therefore, PlayStation®Plus benefits cannot be shared.
The benefits shared with non-subscribing users depends on the type of system and whether it is activated on the subscriber’s account.
Choose either PlayStation 3 or PlayStation 4 for more details.
