 * Azure CLI. You can also run the commands in this article using the [Azure Cloud Shell](/azure/cloud-shell/overview), an interactive CLI shell that runs in your browser or in an app such as Windows Terminal. If you use the Cloud Shell, you don't need to install anything. If you prefer to use the CLI locally, this article requires Azure CLI version 2.36 or later. Run `az --version` to find the version. To locally install or upgrade Azure CLI, see [Install Azure CLI](/cli/azure/install-azure-cli).

-> Azure CLI requires you to be logged into your Azure account. If you're using the Cloud Shell, you're automatically logged into your Azure account. If you're using a local CLI client, you must log into each CLI session. All communication between your Azure CLI shell session and your IoT hub is authenticated and encrypted.

 1. In the CLI session, run the [az extension add](/cli/azure/extension#az-extension-add) command. The command adds the Microsoft Azure IoT Extension for Azure CLI to your CLI shell. The extension adds IoT Hub, IoT Edge, and IoT Device Provisioning Service (DPS) specific commands to Azure CLI. After you install the extension, you don't need to install it again in any Cloud Shell session.
