More about this script

Why use this template?

Use this PowerShell template when you need to find app registrations without a listed owner. It is generated locally and can be reviewed before you run it yourself in your own PowerShell session.

The template uses Microsoft.Graph.Applications and requires Application.Read.All. Output: CSV report. Level: Advanced. Action: Read-only. Risk: Low.

Review before running

The script is generated in your browser. Read it before you run it, and test it outside production first. “Read-only” describes the script itself; anything you add around it can still change data.

Generate the script

  1. Open the template in the PowerShell Builder.
  2. Enter the requested values and review the module, permissions, output and risk.
  3. Generate the script, read it carefully, and test it outside production before use.

The script is generated locally in your browser. Nothing needs to be uploaded to Opselith.

How to use this result

Use this report to identify app registrations where Microsoft Graph returns no listed owners.

When this helps

  • Prepare an application-ownership review before cleanup or credential rotation.
  • Find app registrations that need an accountable technical or business owner.

How to read the result

  • A No owners row means the application owner collection returned no owners for that app registration.
  • The report is about application objects; enterprise application/service-principal ownership is a separate object relationship.

Things to check

  • An ownerless app is not automatically unused or unsafe; confirm dependencies before changing it.
  • Per-application owner lookup failures are reported separately rather than treated as no-owner results.

What to do next: Identify a responsible owner and validate application dependencies before assigning ownership, rotating credentials or retiring the app.
