# Licensing and Activation Keys

Proprietary Activations |

Some development shops maintain their own key generation system to control user access to the software they sell with PxPlus. These applications are encoded with a special owner code (issued by PVX Plus) that permits the generation of activation keys by the software developer. The PxPlus activation utility is used to process the proprietary activation keys, which are recorded as secondary-level package activations.

However, the majority of PxPlus-built applications are sold without the need for secondary activations. Most development shops implement distribution controls within their applications; i.e., password protection.
