The Otus Chromebook App is a custom browser that locks down the testing environment. When students use the App to access an assessment, they are unable to print, copy, go to another URL, or access other applications. Students are locked into an assessment until it is submitted for grading.
The Chromebook App is a Chrome Extension that can only be run in kiosk mode when the Chromebooks are centrally managed with Chrome Device Management.
How to Install the Chromebook App
The following instructions describe how to install the App using Chrome Device Management.
Step 1: Login to the Google Suite admin console at https://admin.google.com
Step 2: Select “Device Management” and then “Chrome Management” under Device Settings.
Step 3: On the next screen select “Device Settings” and then scroll down to the “Kiosk Settings” section.
Step 4: Select the “apps & extensions” link.
Step 5: Select the yellow grid icon that shows “Add Chrome app or extension by ID” upon hover, enter the Otus App ID: kkabgiknkhghephdnkgphaofhjpioogg and press enter.
Step 6: The lockdown app should now show up as a row in the "Kiosks" tab for you to manage as part of your Google Suite.
How to Configure the Starting URL
Our Lockdown Browser Chromebook App has been updated with the JSON setting that allows the starting URL to be configured.
If no JSON settings are configured in the Google management interface, then the App should continue to start on https://my.otus.com/ so existing customers should not be affected.
The Student Experience
Students can launch the locked browser by selecting “Otus” from the Apps link on their login screen.
When the App starts, the login page will appear and the student can login and navigate to the exam.
During an exam, the student will be locked into the testing environment until the assessment is submitted for grading.
Once the exam is complete the user must restart the Chromebook to fully exit the exam.

Proxy Server Troubleshooting
If you receive an error from the App about not being able to connect to the Internet, there may be a problem with a proxy server.Kiosk mode does not work with proxy servers unless a network configuration is defined and applied “by device” instead of “by user”.The following steps can be followed to set up the network configuration “by device”.
Step 1:Login to the Google Suite admin console at https://admin.google.com
Step 2: Select “Device Management” and then “Network” under the Device Settings.
Step 3: Select WiFi or Ethernet.If no networks are defined, then select “Create”.
Step 4: Enter the setting for your network.On the proxy settings, configure the proxy as required and be sure to select “by device” in the “Apply network” section.
Step 5: The final step is to validate that everything is set up correctly. To do this, we recommend testing the network settings with the generic "Kiosk" App with App ID: afhcomalholahplbjhnmahkoekoijban
This App allows you to configure an arbitrary URL (such as www. www.respondus.com) which is displayed when the App enters Kiosk mode.Once networking has been validated with the Kiosk App, you can be confident that App will be able to connect to the Internet via the proxy server.
