Infisical currently only supports two methods for connecting to Azure, which are OAuth and Client Secrets.
Using the Azure Key Vault connection on a self-hosted instance of Infisical requires configuring an application in Azure and registering your instance with it.Prerequisites:
  • Set up Azure and have an existing Key Vault instance.
1

Create an application in Azure

Navigate to Azure Active Directory > App registrations to create a new application.
Azure Active Directory is now Microsoft Entra ID.

Create the application. As part of the form, set the Redirect URI to https://your-domain.com/organization/app-connections/azure/oauth/callback.
The domain you defined in the Redirect URI should be equivalent to the SITE_URL configured in your Infisical instance.

Assign API permissions to the application

For the Azure Connection to work with Key Vault, you need to assign multiple permissions to the application.

​
Azure Key Vault permissions

Set the API permissions of the Azure application to include user.impersonation for the Key Vault API.

Back in your Infisical instance, add two new environment variables for the credentials of your Azure application.
  • INF_APP_CONNECTION_AZURE_KEY_VAULT_CLIENT_ID: The Application (Client) ID of your Azure application.
  • INF_APP_CONNECTION_AZURE_KEY_VAULT_CLIENT_SECRET: The Client Secret of your Azure application.
Once added, restart your Infisical instance and use the Azure Key Vault connection.
To use client secret authentication, ensure your Azure Service Principal has the required permissions and is connected to the Azure Key Vault instances you want to use.Prerequisites:
  • Set up Azure and have an existing Key Vault instance.
  • The service principal must be connected to your target Azure Key Vault instance(s)
