I will use the Azure automation account for this demo since that is free and the most straightforward to set up.

It’s up to you if you want to use it from within your client PC or Windows or Linux Server, or from Automation Account, Azure Function, Azure DevOps, or if you want to create a GitHub workflow for it. Our script will be simple, and it can run from anywhere.

You can use this PowerShell to assign this tag to your VMs: Automate password rotation with PowerShell and Key Vault We are making it simple for this demo, and I will do it for all VMs with the tag VMPasswordReset = Yes. We can also pre-fill VM names in Key Vault as Secret names and let the script change only for VMs where KeyVault Secret names match VM names. Now that we know which VMs we want to exclude, we can enable this for VMs based on a specific Azure Tag, Resource Group, or group membership. VMs using different authentication methods or hardened VMs are also not good candidates.If you have any automation or services that depend on using a local administrator password, you will need to point them to the Key Vault.

The demo script will skip VMs that are not running, but you can easily change that to bring them on before changing the password.

Changing passwords for VMs that are off will not work.

Keep that in mind since this example is not working with that possibility. But if you know the user name, you can still change it via the Azure VM extension. This account user name will not be filled up in the OS Profile of Azure VM.

Migrated VMs will have a historical password from on-premises/another cloud.

Trying to change it via VM extension will fail.

Domain Controllers will not have a local administrator.

Running this script to all VMs in our tenant is not a good idea. Identify VMs for which we want to change the password If you want to build these resources quickly in a new test resource group, check out this PowerShell script that I created: Create-DemoLab.ps1. Prepare the test environmentīefore we start, I will assume that you already have VMs, Automation Account, and Key Vault.

This article will show you how to use Azure Automation Runbook to automatically change VM passwords and save new passwords to Azure Key Vault. This is great for one-time change and changing passwords regularly based on a schedule. After changing passwords, you can save them into the Key Vault or any password manager of your choice. Users tend to enter the same user name and password for all VM resources in Azure. And that can be useful if we are not using LAPS or a similar solution.

This also unlocks the possibility to change local administrator passwords for our Azure VMs programmatically. Or even to create a new account if we don’t remember the user name. This feature relies on Azure Agent and VM extension, and it allows us to reset the configuration of RDP/SSH and the local administrator password.

Below is my code to perform this lookup.Being able to change Azure VM admin password from Azure Portal easily is very convenient. This feature will look up a resource in Azure, and I can then reference this resource and find the password I need. Param keyVaultName string = 'kv-passwords-001'īefore referencing the password in my Key Vault, I need to use Bicep’s “existing” feature. Param keyVaultResourceGroup string = 'rg-keyvault-001' To look up the password in Azure Key Vault, I also need to add a few parameters to the Key Vault I will be using. Param subnetName string = 'snet-demo-001' Param vNetResourceGroup string = 'rg-bicep-demo-001' Param adminUsername string = 'LocalAdmin' Below is the list of parameters I use for the virtual machine I will be deploying. I like to use parameters for all values that can change if I use the same template for multiple deployments. I select my Key Vault, click on “Access policies,” and then mark “Azure Resource Manager for template deployment.” I need to configure Azure Key Vault to allow deployments to read the secrets/passwords stored in the Key Vault. The code I used in the post is on my GitHub Deploying resources using Key Vaults dramatically increases the security and, at the same time, eases the deployments.

Another benefit of using Key Vaults is that the person who deploys the resources does not need to know the password for the resource but only the reference to the Key Vault. Using Key Vault, I can reference a secret that the deployment will look up at deployment time and not display in any log files.

The reason behind using Key Vault is to avoid having any passwords or secrets stored in templates. I have previously written a post on how to use Azure Key Vault with GitHub Actions, and this time I want to show you have to use Key Vault with Bicep deployments in Azure.
