Webroot offers many advanced features to its users, and those who opt for an upgraded plan can even enjoy real-time protection, lightning-fast scans, and identity theft protection. To avail of these smart features, one has to make a Webroot user account and provide the Keycode that comes with the purchase. A Keycode is a 20-digit alphanumeric number that comes with the purchase of any Webroot product. Usually, you can find the Keycode written at the back of the retail card. If you have purchased the software online, the Keycode will be shared with your registered email address.
