This is a beta app meant to be used only by a select group of TAP enterprise customers to experiment with the phone sign-in feature. As such, we are still working on adding usability and accessibility features including support for keyboard interface, dissimilar modes of sensory feedback (e.g., touch/audio), alternative interface (e.g., voice), and allowing the functionality and navigation UI to be exposed and operable. Once this feature is verified, this app will be deprecated and this feature will become part of the Microsoft Authenticator. When this app is released, we will comply with all of the above policies.
