Methods, systems and computer readable media for multi-device single network sign-on are described. For example, a method can include authenticating a first device for network access via a first authentication process, the first device being associated with a user account. The method can also include receiving an access request from a second device associated with the user account, and determining whether the second device is within an access perimeter of the first device. The method can further include permitting the second device to access the network without a second authentication process when the second device is within the access perimeter of the first device.
