Working Modes

1. Kiosk Mode: Kiosk Mode is a feature in Chrome that allows the device to be used in a single-window/single-app kiosk mode. Essentially, it locks away access to the rest of the device. In Kiosk Mode, users are locked onto a single, full-screen Chrome App that they can't change or exit. Harmony has some default apps in this mode. Students can use Chromebooks in Kiosk mode by clicking the Apps link. No sign-in is required in this mode. (See example below)
