Did you ever want to quickly enumerate over all vCenters that are connected with vCAC? without storing hard coded credentials? and never worry when endpoints are added or removed? Here is how …

### try {
# Load PowerCLI
Add-PSSnapin VMware.VimAutomation.Core;
# Allow multiple logins
$null = Set-PowerCLIConfiguration -DefaultVIServerMode 
  ([VMware.VimAutomation.ViCore.Types.V1.DefaultVIServerMode]::Multiple) -Confirm:$false
foreach($me in ($m.ManagementEndpoints |? InterfaceType -eq 'vSphere')) {
  # Get DNS name of endpoint
  [Uri] $UriMe = $me.ManagementUri;
  $ViServer = $UriMe.Host;
  # Load credentials of management endpoint
  $cc = $m.LoadProperty($me, 'Credential');
  $Password = [DynamicOps.Common.Utils.ScramblerHelpers]::Unscramble($cc.Password);
  $ViCred = New-Object System.Management.Automation.PSCredential($cc.Username, 
    (ConvertTo-SecureString -String $Password -AsPlainText -Force));
  $null = Connect-ViServer -Server $ViServer -Port $UriMe.Port 
    -Credential $ViCred -ErrorAction SilentlyContinue;
} # foreach
# all logged in vCenters are in $global:DefaultVIServers
$avm = Get-Vm;
Write-Host ("Enumerating all virtual machines SUCCEEDED: '{0}'." -f $avm.Count);
### try

### finally {
# Clean up
foreach($ViServer in $global:DefaultVIServers) {
  $null = Disconnect-ViServer $ViServer.Name -Confirm:$false;
} # foreach
### } # finally
