Abstract
A method for generating a secure single-tap authentication user interface includes obtaining a screenshot of content from an application operating in an execution environment outside of a trusted execution environment, generating graphical elements of a single-tap authentication user interface, and generating a progress switching layer. Additionally, the method includes responsive to an authentication request, generating a composited display, the composited display comprising the screenshot of content from the application, the graphical elements of the single-tap authentication user interface, and the progress switching layer, passing the composited display from outside the trusted execution environment to the trusted execution environment and displaying, by the trusted execution environment, the composited display as part of a trusted user interface (TUI).
