ChromeOS  — Kiosk Mode Setup Guide

Before you begin

• Your ChromeOS Flex device is enrolled in Google Admin Console
• You can see the device listed under Devices → Chrome → Devices
• You know which Organisational Unit (OU) the device belongs to

Step 0 — Enroll the ChromeOS Flex Device

If the device has not yet been enrolled, follow these steps:

1. Boot the ChromeOS device
2. Connect to Wi-Fi or Ethernet when prompted
3. At the ChromeOS welcome screen, press:
   Ctrl + Alt + E (Enterprise enrolment shortcut)
4. Sign in using your Google Admin / Workspace account
   (Must have permission to enrol devices)
5. When prompted, select the Organisational Unit (OU) where the device should live
   (Example: Signage, Kiosk Devices, Stores, etc.)
6. Click Enroll
7. Once complete, the device will restart and appear in:
   Devices → Chrome → Devices inside Google Admin Console

Note: Device policies will only apply after the device is successfully enrolled and placed in the correct OU.

Step 1 — Add NowSignage as a Kiosk App

Go to Devices → Chrome → Apps & Extensions
Click the Kiosks tab at the top
Select the Organisational Unit (OU) your device is enrolled in from the left panel
Click the yellow + button (bottom right) → Add by URL
Enter the URL:
https://play.nowsignage.com/
Click Save

Note: You will not see individual devices on this screen — that is expected. Apps assigned to an OU automatically apply to all devices in it.

Step 2 — Set NowSignage to Auto-Launch

After saving, NowSignage will appear in the app list on the left

At the top of the app list, locate the Auto-launch app row
Click the None dropdown next to Auto-launch app
Select NowSignage from the options
Click Save in the top right

Note: This ensures the device boots directly into NowSignage without any user interaction required.

Step 3 — Prevent Users from Signing In

Go to Devices → Chrome → Settings → Device tab
Select your OU from the left panel
Use the search bar to find Sign-in settings (Look for Sign-in restriction)

Set Sign-in settings to:
Never allow any user to sign in

Click Save

Note: This locks the device into kiosk mode and prevents anyone from logging in as a regular user.

Step 4 — Apply Settings to the Device

Reboot the ChromeOS Flex device

The device should boot directly into:
https://play.nowsignage.com/ automatically

To manually force a policy refresh (if needed):
Open Chrome on the device and navigate to:
chrome://policy
Then click Reload Policies

Troubleshooting

Settings not applying after reboot
Confirm the device is in the correct OU via
Devices → Chrome → Devices
Click the device and check the Organisational Unit field.

Move button greyed out in Devices list
The device is already in the selected OU — no action needed.
