Abstract

A method and apparatus are for automatically accessing a social network account that provides member information about each of a plurality of social network members. The member information about at least one of the social network members, denoted as a particular member, includes a network detection portion and a security portion. The network detection portion is retrieved from the social network for at least the particular member. A detection is made that the wireless device is within range of a secure wireless network associated with the particular member. The detection uses the network detection portion of the particular member as an input. The security portion of the member information of the particular member is retrieved from the social network. The security portion is used to derive access credentials for the secure wireless network. The derived access credentials are used to securely access the secure wireless network.
