# How to manage MapTiler Engine licenses in MapTiler

This document will show how to manage **Engine License Keys** and explain their administration from your MapTiler account.

_As with any other MapTiler service, the **Engine****app** can be used with a basic **Free license**. After installation, the advanced functions can be unlocked with a license key (only the **Pro** version of the Engine app has a different installer)._

_One **Engine****License Key** can be used to unlock one instance of **Engine app** at a time, for use on a single machine._

## Obtaining and Activating a Key

MapTiler **Engine** license keys can be purchased online with a credit card. In the case of **Pro License,** there is the possibility to pay via a quote & invoice, instead of via card.

After [buying](https://www.maptiler.com/pricing/) any MapTiler **Engine** license, the **License Key** will be sent to the email address associated with your account. The process of activating the Engine app with your Key is described on our [support page](https://docs.maptiler.com/guides/map-tiling-hosting/data-processing/license-activation). This is the only way how to activate your **Engine app**.

Purchased keys can also be added to the MapTiler [Engine administration page](https://cloud.maptiler.com/account/engine/), and be partially managed from there.

The MapTiler administration page can be used to see and deactivate keys, but **cannot be used to activate licenses**. This must be done directly in the **Engine app,** on the machine where the application will be used.

## Key Deactivation

As one key can be activated in a single **Engine app** at a time, it is necessary to deactivate the key on a machine before activating the application again on the new machine. This is done in the **Engine app** and the process is described on our [support page](https://docs.maptiler.com/guides/map-tiling-hosting/data-processing/license-deactivation).

In case of an emergency (i.e. deleted virtual system) it’s possible to deactivate any key on the MapTiler [Engine administration page](https://cloud.maptiler.com/account/engine/) in account settings. This can be done only twice per year.
