You can remove a device from your Lookout Security subscription using a web browser on any internet-connected device. Here’s how:
Visit Lookout Security’s website and log in with your account details.
Click My Devices at the top of the page and pick the device you want to remove.
Click Deactivate from Account.
Please note that this will leave the device unprotected from the latest malware threats. Therefore, once you’ve removed a device from Lookout Security, I recommend installing an alternative antivirus on that device. Norton is a great choice that offers a lot of much better features than Lookout Security, including a really good app advisor. Norton also offers a 60-day money-back guarantee on all its plans.
