Abstract: An authentication process in a network environment provides a remote user with secured access to an enterprise network based on recognition of a third-party security token. The method includes authenticating the user against a plurality of third-party security tokens, wherein the third-party security tokens originate from a range of different partner home sites. The remote user, prior to obtaining secured access to the enterprise network, is not known to the enterprise network, and does not need to be associated with any security tokens previously originating from the enterprise network. The enterprise network is provided with the ability to rely upon third-party security tokens to authenticate the remote user.
