Create a customer identity and access management (CIAM) tenant (preview)

Azure Active Directory (Azure AD) offers a customer identity access management (CIAM) solution that lets you create secure, customized sign-in experiences for your customer-facing apps and services. With these built-in CIAM features, Azure AD can serve as the identity provider and access management service for your customer scenarios. You'll need to create a customer tenant in the Microsoft Entra admin center to get started. Once the customer tenant is created, you can access it in both the Microsoft Entra admin center and the Azure portal.

In this article, you learn how to:

  • Create a customer tenant
  • Switch to the directory containing your customer tenant
  • Find your customer tenant name and ID in the Microsoft Entra admin center


  • An Azure subscription. If you don't have one, create a free account before you begin.
  • An Azure account that's been assigned at least the Contributor role scoped to the subscription or to a resource group within the subscription.


Microsoft Entra External ID is currently in preview. See the Supplemental Terms of Use for Microsoft Azure Previews for legal terms that apply to Azure features and services that are in beta, preview, or otherwise not generally available.

  6. If you're creating a customer tenant for the first time, you have the option to create a trial tenant that doesn't require an Azure subscription. Otherwise, use the Azure Subscription option to continue to the next step.

Get the customer tenant details

If you're not sure which directory contains your customer tenant, you can find the tenant name and ID both in the Microsoft Entra admin center and in the Azure portal.

  1. To make sure you're using the directory that contains your customer tenant, select the Directories + subscriptions icon in the toolbar.

  2. On the Portal settings | Directories + subscriptions page, find your customer tenant in the Directory name list, and then select Switch. This step will bring you to the tenant's home page.

  3. Select the Overview tab at the top of the page. You can find the tenant Name, Tenant ID and Primary domain under Basic information.

You can find the same details if you go to Azure Active Directory either in the Microsoft Entra admin center or in the Azure portal. On the Azure Active Directory page, you can find the tenant Name, Tenant ID and Primary domain under Overview > Basic information.
