Then, follow the steps below to deploy OTG for Chromebooks using Google Workspace. As a best practice, always test your deployment using a limited test group with just one or two users first before full deployment.
Log into your Google Workspace account with administrative access.
From the main menu, go to Directory > Organizational units and ensure you have created the organizational unit (OU), or units, to which you are deploying OTG for Chromebooks. The example here shows two OUs - one for deploying to all students and one for teaching staff:
For more information on how the organizational structure work in Google Workspace, see https://support.google.com/a/answer/4352075 .
Upload the .pem WebTitan certificate to Google Workspace. See Importing a WebTitan TLS Root Certificate in Google Workspace.
Follow these steps to add the WebTitan Chromebook OTG app to the OU from the Google Play Store:
An app and its settings are applied to the users in the current selected organizational unit. This means if a user logs into a personal device with the same username, WebTitan filtering will be applied to them on this personal device.
From the main menu go to Devices > Chrome > Apps & Extensions > Users & Browsers.
In the left pane, select the OU you want this app to be available to (a child OU inherits access to apps from its parent OU).
Click in the bottom right of the screen and select the Add from Google play button.
