Hello @EnterpriseArchitect

To rotate the client secrets in multiple subscriptions, you can use PowerShell scripts.

The tutorial you mentioned is a good starting point, but it only covers rotating secrets for a single subscription. To rotate secrets for multiple subscriptions, you can use the Azure PowerShell module and the Set-AzKeyVaultSecret cmdlet.

You can write a script that loops through each subscription, retrieves the necessary information (such as the Key Vault name and secret name), and then rotates the secret using the Set-AzKeyVaultSecret cmdlet.

Here's an example script that rotates a secret for multiple subscriptions:

# Connect to Azure 
Connect-AzAccount 
# Define the subscriptions to rotate secrets for 
$subscriptions = @("subscription1", "subscription2", "subscription3")
# Loop through each subscription 
foreach ($subscription in $subscriptions) {
	# Select the subscription 
	Set-AzContext -Subscription $subscription
	# Retrieve the Key Vault and secret information 
	$keyVaultName = "mykeyvault" 
	$secretName = "myclientsecret"
	# Generate a new secret value 
	$newSecretValue = New-Guid 
	# Rotate the secret 
	Set-AzKeyVaultSecret -VaultName $keyVaultName -Name $secretName -SecretValue $newSecretValue
}
# Disconnect from Azure
Disconnect-AzAccount 

This script connects to Azure, defines the subscriptions to rotate secrets for, loops through each subscription, retrieves the Key Vault and secret information, generates a new secret value, and then rotates the secret using the Set-AzKeyVaultSecret cmdlet.

Note that you'll need to modify the script to match your specific Key Vault and secret names, and generate a new secret value using your own method.
