# License

{% hint style="info" %}
**File-based configuration**

You can add `_FILE` to individual variables to provide their configuration in a separate file. Refer to [Keeping sensitive data in separate files](/deploy/host-n8n/configure-n8n/basic-configuration.md#keeping-sensitive-data-in-separate-files) for more details.
{% endhint %}

To enable certain licensed features, you must first activate your license. You can do this either through the UI or by setting environment variables. For more information, see [license key](/deploy/host-n8n/configure-n8n/manage-your-license.md).
