Systems for providing an integrated user interface and/or authenticating a user or a device are disclosed. A system for providing an integrated user interface includes a central control server having a user interface engine and a backend application programming interface engine, a user device communicatively coupled to the central control server that is configured to provide a user interface, and a plurality of backend servers communicatively coupled to the central control server. The backend application programming interface engine generates and supplies application programming interfaces to the backend servers, the application programming interfaces including programming instructions thereon that direct a corresponding one of the plurality of backend servers to provide data to the central control server. The user interface engine generates the integrated user interface comprising the data received from the plurality of backend servers and provides the integrated user interface to the user device for display to a user.
