Updating Securly Classroom Lost Mode Kiosk

Google is discontinuing support for Chrome apps that use kiosk mode starting in July 2025, extending through 2028 for some devices with long-term support (LTS) (see this article). You may already be receiving a banner in Google Admin with a notification.

We have a replacement available for the Securly Classroom Lost Mode kiosk application, which will now run as a web app.

Remove the old kiosk app

In Google Admin Console, navigate to Devices > Chrome > Apps & Extensions and select the OU that was previously configured for Lost Mode.

Go to the Kiosks tab.

Remove the old kiosk with the extension ID: jlchfbgflflmmcoeagcmfkhlmbofojbm

Configure the new kiosk app

In Securly Classroom, navigate to Settings > Deployment > Google.

Copy the Chrome Lost Mode URL.

In Google Admin Console, on the Kiosks tab of the OU for lost devices, click the + icon at the bottom right corner and select “Add by URL”

Paste the URL copied from Securly Classroom and click on SAVE.
