### About FlexLM License Server Manager

`lmadmin` or `lmgrd` FlexLM daemons are supplied by Unity x Pixyz. Its job is to communicate with the application, and receive the license request from it. It then passes the request to the vendor daemon.

### About Pixyz Vendor Daemon

Specific to Unity x Pixyz Products, `Pixyz Vendor Daemon` job is to process the license request and to either grant it or deny it, depending on the number of available licenses, and predefined license usage constraints.

### About Pixyz License File

Available after completed Unity license purchase for a Pixyz entitlement, and available for generation on your [Pixyz user portal](https://www.pixyz-software.com/my-account/license-management), this license file holds detailed license information such as the quantity and time extent of the license.

### About Pixyz license token(s)

Pixyz relies on a token-based licensing mechanism to protect its software integrity and compartimentalize its software portoflio.
Pixyz SDK automatically configures itself at startup, during the initialization and license configuration phases. See [Setup Guides](./../python) samples.

> **Important:**
>
> Tokens are proprierary to Pixyz and mandatory for a correct execution of the software. Default licensing behavior or token management within Pixyz execution must not be altered or modified.
