1. A computer-implemented authentication system, comprising: an IP-based capable phone for enabling communications between a user and a party at a destination; a pre-authentication module for utilizing pre-authenticated credentials available from a communications server, to replace information that would otherwise be gathered from the user via a dialog, to enable automatic authentications with subsequent components instead of requiring user interaction for authentication; a trust component of the pre-authentication module for receiving the pre-authenticated credentials from the communications server to enable the user to authenticate and obtain access to the phone without a log-in process, the pre-authenticated credentials are received via a media session protocol, which is a session initiation protocol (SIP), the pre-authenticated credentials have been authenticated to provide a basis for communicating trust and include at least one of a device identity data or user identity data; an application component comprising at least one application of at least one system for providing an application service of the phone that is exposed based on the pre-authenticated credentials, the application service facilitates communications between the user and the destination; and a microprocessor that executes computer-executable instructions in a memory associated with at least one of the phone, the pre-authentication module, the trust component, or the application component.
