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, a user is locked onto a single, full-screen chrome App that they can't change or exit. Harmony has some default apps on 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)


  2. User Mode: Students will use this mode when they log in through My Harmony Portal and then have access to all apps and Chrome Browser.  They will click on "Add person" on the main screen. Sign in is required.
