Register Windows Admin Center with Azure

Applies to Azure Stack HCI version 20H2; Windows Server 2019

To use Azure services with Windows Admin Center, you must first install Windows Admin Center on a management PC and register your Windows Admin Center gateway. This is a prerequisite for registering a cluster with Azure.


In order to use Windows Admin Center to register Azure Stack HCI clusters, your Windows Admin Center gateway must be registered to an Azure Active Directory (Azure AD) application ID that is approved by your organization's Azure AD admin. Register Windows Admin Center on the same management PC you plan to use to register your cluster(s), using the same Azure Active Directory (tenant) ID.

Complete the registration process

Launch Windows Admin Center and select the Settings gear icon in the upper right, which will take you to your Account page. Then, from the Gateway menu at the left, select Azure, and then click Register.

Select Settings > Gateway > Azure, then click Register

To register Windows Admin Center, follow these steps:

  1. Select an Azure cloud from the dropdown menu.

  2. You'll be provided with a unique code. Click the Copy button to the right of the code. Click Enter the code, which will open up another browser window into which you can paste the code displayed on your app or device.

    Copy the unique code, click enter the code, and paste it into the dialog box

  3. After pasting in the code, you'll be notified that you're about to be signed in to Windows Admin Center on a remote device or service. Enter your email or phone number. If your device is managed, you will be taken to your organization's sign-in page for authentication. Follow the instructions and enter the appropriate credentials. You may be asked to confirm that you're trying to sign into Windows Admin Center. Select continue.

    Sign in to Windows Admin Center using your email or phone number

    You should see the following message: "You have signed in to the Windows Admin Center application on your device." Close the browser window to return to the original registration page.

  4. Connect to Azure Active Directory by supplying your Azure Active Directory (tenant) ID and application ID. If you already have an Azure tenant ID and you've followed the preceding steps, the tenant ID field may be pre-populated and may contain multiple options. Select the correct tenant ID.

    If your Azure AD administrator has provided you with an application ID, click Use existing, and an empty field will appear for you to enter the ID provided by your admin. After entering your ID, Windows Admin Center will confirm that an account with that ID is found. If you have an existing ID but don't know what it is, follow these steps to retrieve it. If your organization didn't provide you with an existing ID, leave Azure Active Directory application set to Create New.

    Connect to Azure Active Directory by supplying your existing Azure Active Directory (tenant) ID and application ID, or creating a new application ID

  5. Click Connect. If you're an Azure AD admin or if you used an existing application ID, you should see a confirmation that you are now connected to Azure AD. You may see a Permissions requested dialog box; click Accept. Select Sign in to sign into Windows Admin Center with your Azure account. If you're not an Azure AD admin and you created a new application ID upon registration, you'll need to ask your Azure AD admin to grant consent to the new application ID by following the instructions in step 6 below.

  6. If you are an Azure AD admin, grant permissions in the Azure portal by navigating to Azure Active Directory, then App registrations. Select All applications and search for WindowsAdminCenter. Select the display name that matches the address of the Windows Admin Center system you're registering. Take note of the Application (client) ID displayed near the top of the page, as you may need to provide it to one or more users in your organization so they can register Windows Admin Center on their PCs. Next, navigate to API permissions and select Grant admin consent. If you plan to use the same application ID for multiple users, proceed to step 7; otherwise, you're done.

  7. For convenience and ease of management, it's possible to enable multiple users in an organization to register Windows Admin Center on their PCs using the same Azure app ID. To do this, all users must register Windows Admin Center to the same domain and port, usually https://localhost:6516. This also requires the Azure AD admin to take an extra step and add redirect URIs in the Azure portal.

    In the Azure portal, select Authentication under Manage from the toolbar on the left. In the Redirect URIs box, you will see an existing URI representing the first Windows Admin Center system that registered to the app ID. Select Add URI and add two new redirect URIs: http://localhost:6516 and https://localhost:6516. Select Save.

    To enable multiple users in an organization to register Windows Admin Center using the same Azure app ID, add redirect URIs


    Make sure to provide your users with the correct Azure tenant ID and the application ID from step 6, and tell them to select Use existing application ID when registering Windows Admin Center. Note that if an Azure AD admin doesn't add redirect URIs and more than one user tries to register Windows Admin Center to the same app ID, the user(s) will get an error that the reply URL doesn't match.

  8. Once Windows Admin Center is registered with Azure, you're ready to register your Azure Stack HCI cluster with Azure.

Unregister Windows Admin Center

To unregister Windows Admin Center, select the Settings gear icon in the upper right. Then, from the Gateway menu at the left, select Azure, then Unregister, then Confirm.

This will remove the association between Windows Admin Center and the Azure AD app ID that was provided by your Azure AD admin or created when you registered Windows Admin Center. It will not delete the Azure AD app nor affect any Azure services used by servers or clusters managed by Windows Admin Center.
