Get name of Farm account using Powershell

Question

How can I get the name of the Farm account ? I can see it listed in Get-SPManagedAccount, but do not see any properties on the SPManagedAccount objects to be able to dynamically filter by and determine if it's the farm administrator.

Answer 1

Use (Get-SPFarm).DefaultServiceAccount.Name should give you the Farm Account

Answer 2

this is what i used to change the farm account Get-SPManagedAccount

New-SPManagedAccount

Remove-SPManagedAccount

Set-SPManagedAccount

Answer 3

This will give you the Farm Administrators:

$ca = [Microsoft.SharePoint.Administration.SPWebService]::AdministrationService.WebApplications | Select -First 1
$root = $ca.Sites["/"].RootWeb
$grp = $root.SiteGroups["Farm Administrators"]
$grp.Users

and

Get-SPManagedAccount will give you managed accounts

There should only be the farm admin common in these two groups
