When working in my Azure labs I tend to end up with a lot of Azure App Registrations. Recently I had hundreds and hundreds of them in the directory. Its been a while since I cleaned this up. I needed to clean this out and did not want to do this manually through the portal. PowerShell to the rescue.
I pulled together a script that will place your app registrations in a variable. It will then loop through the app registrations to remove them. Note you will be prompted with a confirmation to remove each one.
You can download the script here: https://github.com/Buchatech/Delete-Azure-App-Registrations-
