Accessing Windows Credential Manager from PowerShell

In powershell5 type:

   Install-Module CredentialManager -force

Then

   New-StoredCredential -Target $url -Username $ENV:Username -Pass ....

and later

   Get-StoredCredential -Target .... 

Source code for the module is https://github.com/davotronic5000/PowerShell_Credential_Manager

You'll need to access the Win32 API to interact with the Credential Manager.

CredMan.ps1 from the Technet scripting gallery nicely demonstrates this.

For simpler usage patterns, like just listing principals or adding new credentials, you can also use cmdkey, a built-in Windows Command-line utility for credential management

For reusing stored Credentials in PowerShell, this guy seems to have found a way to build a PSCredential from a Generic Credential handle from the Credential Store, using a technique similar to that of CredMan.ps1: Get-StoredCredential

According to the docs, the PasswordVault class isn't supported on Windows Server 2008 R2.

Minimum supported server Windows Server 2012

SecretManagement and SecretStore from Microsoft appear to be the official solution. They were officially released on March 25, 2021. The secret can be a credential.

Install-Module Microsoft.PowerShell.SecretManagement
Install-Module SecretManagement.JustinGrote.CredMan  # windows credential manager
Register-SecretVault SecretManagement.JustinGrote.CredMan
Set-Secret -Name TestSecret -Secret "TestSecret"
Get-Secret -Name TestSecret -AsPlainText
