Abstract

In embodiments of restricted execution modes, a mobile device can display a device lock screen on an integrated display device, and transition from the device lock screen to display a shared space user interface of a shared space. The transition to display the shared space user interface is without receiving a PIN code entered on the device lock screen. The mobile device implements a restricted execution service that is implemented to activate a restricted execution mode of the mobile device, and restrict access of a device application to device content while the restricted execution mode is activated. The restricted execution service can also allow a shared device application that is included in the shared space access to the device content while the restricted execution mode is activated.
