Using Credential Manager in PowerShell

Using PowerShell remoting can be a fantastic experience, but the number of  times I had to enter credentials to make a new pssession is getting out of hand, or to put it better a painful hand. Wouldn’t it be great if you could store the credentials somewhere safe and retrieve it when necessary? Fortunately, you can! Since a long time Windows has had the option to store credentials in a local secured database and use it when needed. This is known as the “Credential Manager” and can be located in the control panel.


Within this tool you can store credentials for both Web Sites and network resources such as remote servers. Wouldn’t it be really cool if you could store credentials there once and retrieve them using PowerShell? Luckily, you can! Someone actually created a PowerShell Module called “CredentialManger” that does just what this post is about.

First, we need to install the module. It’s located in the PowerShell Gallery so you need to trust that Gallery (Use Set-PSRepository) and have NuGet installed. If you didn’t do this just yet, you’ll get additional messages, accept them to continue.

Install-Module -Name "CredentialManager"

To see what the module exposes use:

Get-Command -Module "CredentialManager"


Let’s start with creating new credentials. The CMDLET “New-StoredCredential” seems to do just that. I’ve constructed the following code to create a new set of credentials in the credential manager. The first part prompts for input and stores it in the $Secure variable. Next I create the new object and store it as persistant accross sessions by specifying the “-Persist” parameter. As it’s also a generic type of credentials I explicitly specify that also.

$Target = "YourServerName"
$UserName = "Administrator"
$Secure = Read-host -AsSecureString
New-StoredCredential -Target $Target -UserName $UserName -SecurePassword $Secure -Persist LocalMachine -Type Generic

The output will result in this:


Using the help system I figured out that “Get-StoredCredential” retrieves the objects stored in credential manager. To select the credentials we just created the “-Target” property needs to be specified. In this case we will be referring to the target server we just created, “servername”. Use this command to get all properties into a credentialized object:

Get-StoredCredential -Target "servername" –AsCredentialObject

Retreiving a single pair of credentials is easy, right!? Now what I am after is credentials that are stored for the use in PowerShell remoting. In my specific case to connect to a remote server I’m managing.

Eventually, I created this command-line:

Enter-PSSession -ComputerName "servername" -Authentication Credssp -Credential (Get-StoredCredential -Target "servername")

As you can see the “Get-StoredCredential” needs a target parameter to retrieve the credentials. That outputs a username and password (as System.Security.SecureString) that is then passed to the “Enter-PSSession” cmdlet.


My servername in this case is “WHV” and the credentials are stored as “HyperVManager/WHV”.

Removing credentials using the same module is very straightforward. The “Remove-StoredCredentials” does the trick. Again pointing it to the credentials using the “-Target” parameter.

Remove-StoredCredential -Target "servername"

I hope that this post helps you to use credentials in a safe and easy manner.
