unauthorized use

Using without permission

Unauthorized use is employing something—typically property, software, or access credentials—without permission from the owner or controlling authority.

The phrase appears frequently in legal and technical contexts: unauthorized use of a credit card, unauthorized use of company resources.

Warning labels often state that unauthorized use is prohibited and may be prosecuted.
