Azure AD App + PowerShell
Create Azure AD Application with Configurations Using PowerShell
There are different ways that you can create an Azure AD application aka Azure AD app registration. Sometimes, you may have to create it using the portal or by using PowerShell modules. When you use PowerShell to do this, you can save the script and reuse the same in the future, one of the many advantages of using this approach is that it will help you remove human errors. Let’s see how we can do this.
Before we run the command to create the application, make sure that you have installed the AzureAD module. Open your PowerShell ISE with administrator access, and then type the preceding command.
PS C:\WINDOWS\system32> Install-Module AzureAD
This will install the module for you. You can see this in the modules list in the ISE. Click on the refresh button if you don’t see it.
Now run the command “Connect-AzureAD” to connect to your Azure Account. If you have multiple directories with your account, then you must connect it with the tenant parameter. You can get the tenant id from the Tenant Properties window. Switch to the directory in the Azure Portal and search for the Tenant Properties in the search bar. Copy the Tenant ID from there and run it with the preceding command.
Connect-AzureAD -TenantId YourTenantIDHere
Login again if you are asked again. And you are ready to run the command to create the AD application.
Here the parameter “-Oauth2AllowImplicitFlow” is to enable the OAuth flow and the -AvailableToOtherTenants is to make sure that my app is available to other tenants. You can see more options here.
