iLok Definition

iLok is a separate software that manages authorizations . Having an iLok USB allows you to carry your software licenses on a physical drive between a studio, your home and any other location you may be using iZotope software.

So this iLok USB is for users of the iLok software who carry their personal licenses with them from place to place. It appears to be for the professional audio community - studio musicians and editors and content generators.
