Rotate storage account access keys with PowerShell

This script creates an Azure Storage account, displays the new storage account's primary access key, then renews (rotates) the key.

This sample requires Azure PowerShell. Run Get-Module -ListAvailable Az to find the version. If you need to install or upgrade, see Install Azure PowerShell module.

Run the Connect-AzAccount cmdlet to connect to Azure.

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

Sample script

# this script will show how to rotate one of the access keys for a storage account

# get list of locations and pick one
Get-AzLocation | select Location

# save the location you want to use  
$location = "eastus"

# create a resource group
$resourceGroup = "rotatekeystestrg"
New-AzResourceGroup -Name $resourceGroup -Location $location 

# create a standard general-purpose storage account 
$storageAccountName = "contosotestkeys"
New-AzStorageAccount -ResourceGroupName $resourceGroup `
  -Name $storageAccountName `
  -Location $location `
  -SkuName Standard_LRS `

# retrieve the first storage account key and display it 
$storageAccountKey = (Get-AzStorageAccountKey -ResourceGroupName $resourceGroup -Name $storageAccountName).Value[0]

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

# re-generate the key
New-AzStorageAccountKey -ResourceGroupName $resourceGroup `
    -Name $storageAccountName `
    -KeyName key1

# retrieve it again and display it 
$storageAccountKey = (Get-AzStorageAccountKey -ResourceGroupName $resourceGroup -Name $storageAccountName).Value[0]
Write-Host "storage account key 1 = " $storageAccountKey
