Where to find Azure Tenant ID in Azure Portal?

Some of the documentation about Azure from Microsoft can be confusing and missing, including one I get ask ‘Where is the Tenant ID’. Below I give 3 locations, which there is probably, on where to find the Tenant ID in the portal. I have also added how to get the Tenant ID with the Azure CLI.

The Tenant is basically the Azure AD instance where you can store and configure users, apps and other security permissions. This is also referred to as the Directory in some of the menu items and documentation. Within the Tenant you can only have a single Azure AD instance, but you can have many Subscriptions associated with it. You can get further information from here https://docs.microsoft.com/en-us/microsoft-365/enterprise/subscriptions-licenses-accounts-and-tenants-for-microsoft-cloud-offerings?view=o365-worldwide

Azure Portal

Azure Active Directory

If you use the Portal menu, once signed in, then you can select the ‘Azure Active Directory’ option.

This will load the Overview page with the summary of your Directory including the Tenant ID.

You can also go to this URL when signed in: https://portal.azure.com/#blade/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/Overview

Azure AD App Registrations

When configuring external applications or internal products to talk, you can use App Registrations or also know as Service Principal accounts. I know when using the REST API or the Azure SDK you will need the Tenant ID for the authentication, so within the registered app you also get the Tenant ID.

When in the Azure AD, select the ‘App registrations’ from the side menu. Find or add your App then select it.

From the App Overview page you can then find the Tenant ID or also known here as the Directory ID.

Switch Directory

If you have multiple Tenants then you can switch between the Tenants you have access to by switching Directory.

You can do this by selecting your Avatar/Email from the top right of the Portal, which should open a dropdown with your details. There will then be a link call ‘Switch directory’, and by clicking this you can see all the directories you have access to, what your default directory is and switch which one you are on.

As mentioned before the Directory is another word used my Azure for Tenant, so the ID you the see in this view is not just the Directory ID but also the Tenant ID.
