A first computing device receives a service access request to access a service provided by another computing device, the request including user authentication characteristics of a user. The first computing device forwards the service access request to the other computing device. The first computing device receives a user interface configuration file from the other computing device, that, when executed by the second computing device, enables the second computing device to display a user interface that provides access to the service. The first computing device modifies the user interface configuration file based on the user authentication characteristics to provide selective access to the service. The first computing device transmits the modified user interface configuration file to the second computing device, that, when executed by the second computing device, enables the second computing device to display a modified user interface that provides selective access to the service.
