CompTIA ITF+ FC0-U61 (V5) Practice Question

A product key is an alphanumeric code used to verify that a user has a legitimate license for a software program. It is a common method for preventing software piracy by ensuring that each copy of the software was legally obtained and is not being used on more devices than the license permits. A password is used to control user access to a system or application, not to validate the software's license. While some keys might unlock additional features, the primary purpose of a product key is license validation. Finally, a product key is associated with the software license, not with uniquely identifying a specific user.
