# Adding an Azure Key Vault Server

You can add or modify an Azure Key Vault server with or without access node from the Metallic console.

## Before You Begin

- If you plan to use IAM AD APP authentication type, you must register application with Microsoft Entra ID and note the Tenant ID (directory ID), Application ID, and Application Secret.

- Set Key Vault to use the Azure role-based access control permission model under Access configuration in Azure Portal.
