Systems and methods are provided that may be implemented to secure a publicly-hosted web application so that it will render only within the determined context of a trusted client application. Such an authentication decision may be made, for example, using front-end web application code that is rendered in a client web view together with client application code to authenticate the client application context in which the web page is rendered. In this way, the web application may validate that it is being rendered in the context of a trusted and/or well-known client application rendering engine/environment.
