# Coffre-fort des connexions

Le coffre de connexions vous permet de configurer une chaîne de connexion pour vous connecter à votre base de données que vous pouvez utiliser globalement pour les éléments SQL basés sur [éléments de sécurité](/fr/form-management/security/security-items/sql-security.md), panneaux, [réponses](/fr/form-management/form-designer/answers/answer-types/creating-new-type/lists/sql-server-lists.md) ou [tâches](/fr/form-management/tasks/task-items/sql-query-task.md). 

{% hint style="info" %}
En utilisant une chaîne de connexion globale, vous pouvez rendre la chaîne de connexion disponible pour tous les utilisateurs sans divulguer les détails réels de la chaîne de connexion, car les utilisateurs verront uniquement le nom de la connexion.
