According to the script you provide, you use Az module. So if you want to choose which Azure subscription you use, you need to use the command Select-AzSubscription. Besides, you also can add -Subscription "<subscription Id>" in Connect-AzAccoun to ensure when you login, you choose the right subscription.

For example

1. Create the service principal

Import-Module Az.Resources # Imports the PSADPasswordCredential object
$credentials = New-Object Microsoft.Azure.Commands.ActiveDirectory.PSADPasswordCredential -Property @{ StartDate=Get-Date; EndDate=Get-Date -Year 2024; Password=<Choose a strong password>}
$sp = New-AzAdServicePrincipal -DisplayName ServicePrincipalName -PasswordCredential $credentials

2. assign the role to the service principal. For example, assign Contributor role to the sp at the subscription level

New-AzRoleAssignment -ApplicationId <service principal application ID> -RoleDefinitionName "Contributor" `
-Scope "/subscriptions/<subscription id>"

3. Script

$appId = "your sp app id"
$password = "your sp password"
$secpasswd = ConvertTo-SecureString $password -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ($appId, $secpasswd)

Connect-AzAccount -ServicePrincipal -Credential $mycreds -Tenant <you sp tenant id>
Get-AzSubscription -SubscriptionName "CSP Azure" | Select-AzSubscription

$resourceGroup = "nora4test"

$AccountName = "qsstorageacc"

$Key = (Get-AzStorageAccountKey -ResourceGroupName $resourceGroup -Name $AccountName)[0].Value

Write-Host "storage account key 1 = " $Key
