Verify first-party Microsoft applications in sign-in reports

When you are reviewing your sign-in reports, you may see an application in your sign-in report that you don’t own and want to identify the application. You also may wonder how you signed into that app, as you don’t remember accessing the app.

Here is an example of a sign-in report:

An example of a sign-in report in Azure Active Directory.

For example, when you access, the application shown in the sign-in log may say dev-rel-auth-prod, which is not descriptive regarding

Though the apps listed in sign-in reports are indeed owned by Microsoft, and are not suspicious applications, there is a way that you can verify whether an Azure AD service principal found in your AAD logs is owned by Microsoft.

Verify a first-party Microsoft Service Principal in your AAD tenant

  1. Visit the AAD Enterprise Applications blade

  2. Select All applications in the left-hand menu.

  3. In the Application Type drop-down menu, select Microsoft Applications and hit apply. All applications listed here are owned by Microsoft.

    Select Microsoft Applications in the Application Type drop-down menu.

  4. In the search box below the selectable drop-down menus, filter the list by adding a specific Display Name or Application ID.

    Enter a display name in the search box.

  5. Select the desired app, then select Properties in the left-hand menu to open the listed app's properties and confirm the message that:

    You can’t delete this application because it’s a Microsoft first party application.

    A message that displays the statement you can’t delete this application because it’s a Microsoft first party application.

  1. Open the Azure Active Directory Module in PowerShell

  2. In the PowerShell module, enter the following cmdlet:

    Get-AzureADServicePrincipal -Filter "DisplayName eq '(DISPLAY NAME)’" | fl *

    Replace (DISPLAY NAME) with the app’s actual display name.

  3. Review the result's AppOwnerTenantId.

    The output of a request to show the Azure AD service principal.

    In the previous screenshot, f8cdef31-a31e-4b4a-93e4-5f571e91255a is the Microsoft Service's AAD tenant ID.
