Azure VM: reset local user account password

Question

folks, I have about 200 az vm, contains local user account. I need to reset password for all vms. Now I can do it through portal fine, but like to do scripting.

I tried with
$Computer = "TestVM"
$vmcomp = Get-AzVM -Name $Computer
$vmName = $vmcomp.Name
$resourceGroupName = $vmName.ResourceGroupName
$location = $vmName.Location
$Password = "*P@ssword2022!!"
$UserName = "AzureVM"

        Set-AzureRmVMAccessExtension -ResourceGroupName $resourceGroupName -VMName $vmName -Name $name -Location $location -typeHandlerVersion "2.0" -ForceRerun  

but didn't work, can someone give me examples or any ideas here

Thanks In Advance......

Hi @Arif Usman ,

The Az is the newer module and the replacement for the older AzureRM module.
I would recommend to use the Az only.
https://learn.microsoft.com/en-us/powershell/azure/new-azureps-module-az?view=azps-8.2.0

To uninstall the AzureRM module you could try the Uninstall-AzureRM cmdlet (which is in the Az.Account module): https://learn.microsoft.com/en-us/powershell/module/az.accounts/uninstall-azurerm?view=azps-8.2.0

Some more useful information you will find here:

Answer 2

@Andreas Baumgarten thank you for your reply.
Two things, what if i don't know password for vm. In portal i can easily reset password.
2nd. I am getting following error message when i ran set-azvmaccessextention

So i tried following from https://learn.microsoft.com/en-us/azure/virtual-machines/automatic-extension-upgrade

Set-AzVMExtension -ExtensionName "Microsoft.Azure.Monitoring.DependencyAgent" `  
    -ResourceGroupName "myResourceGroup" `  
    -VMName "myVM" `  
    -Publisher "Microsoft.Azure.Monitoring.DependencyAgent" `  
    -ExtensionType "DependencyAgentWindows" `  
    -TypeHandlerVersion 9.5 `  
    -Location WestUS `  
    -EnableAutomaticUpgrade $true  

no luck

Hi @Arif Usman ,

please take care about the different modules! Az module is not compatible with the AzureRM module!
Use only one of the modules.
Also make sure you are using the latest version of the PowerShell module.

Not sure what do you mean with "what if i don't know password for vm" ?
You are setting the new password ( $Password = "*P@ssword2022!!" ) of the local user ( $UserName = "AzureVM" ). That's it.

If you like to try a different approach.
This is an option to change the password of a local user in a VM as well: https://github.com/abaumgarten42/Azure_Stuff/tree/main/Azure_VMs/RunPowerShellScriptsOnVMs
You need 2 PowerShell scripts on you computer:
RunPSonVM-Reset-PwLocalUser.ps1 starts the PS script Reset-PwLocalUser.ps1 on the defined Azure VM and resets the password of the defined local user
