Export secrets and certificates for app registrations

This PowerShell script example exports all secrets and certificates for the specified app registrations from your directory into a CSV file.

If you don't have an Azure subscription, create an Azure free account before you begin.

This sample requires the AzureAD V2 PowerShell for Graph module (AzureAD) or the AzureAD V2 PowerShell for Graph module preview version (AzureADPreview).

Script explanation

The "Add-Member" command is responsible for creating the columns in the CSV file. You can modify the "$Path" variable directly in PowerShell, with a CSV file path, in case you'd prefer the export to be non-interactive.

Command Notes
Get-AzureADApplication Retrieves an application from your directory.
Get-AzureADApplicationOwner Retrieves the owners of an application from your directory.
