# Gérer la clé principale

Utilisez ***Fichier*** – ***Gérer la clé principale*** pour chiffrer votre espace de travail SQLite ou XML.

La clé principale empêche les utilisateurs non autorisés d'accéder à l'espace de travail sans la connaître. Il est fortement recommandé d'appliquer une clé principale à l'espace de travail si vous utilisez Remote Desktop Manager dans un environnement portable (c'est-à-dire, une clé USB, un disque dur USB).

{% hint style="danger" %}
Si vous perdez votre clé principale, Devolutions ne peut pas récupérer vos données. Assurez-vous de mémoriser votre clé principale ou de la sauvegarder dans un endroit sûr.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/rdm/fr/ribbon-menu-bar/file/manage-master-key.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
