A single-app kiosk uses the Assigned Access feature to run a single app above the lock screen. When the kiosk account signs in, the app is launched automatically. The person using the kiosk cannot do anything on the device outside of the kiosk app.
If the kiosk app is closed, it will automatically restart.
When you are in kiosk mode, you can press the Ctrl + Alt + Delete keys to exit kiosk mode.
