Get-Credential (Microsoft.PowerShell.Security) - PowerShell (2024)

Gets a credential object based on a user name and password.

Syntax

Get-Credential [[-Credential] <PSCredential>] [<CommonParameters>]

Get-Credential [-Message <String>] [[-UserName] <String>] [-Title <String>] [<CommonParameters>]

Description

The Get-Credential cmdlet creates a credential object for a specified user name and password. Youcan use the credential object in security operations.

The Get-Credential cmdlet prompts the user for a password or a user name and password. You can usethe Message parameter to specify a customized message for the prompt.

In Windows PowerShell 5.1 and earlier, Windows presents a dialog box to prompt for a user name andpassword. In PowerShell 6.0 and later, the prompt is presented in the console for all platforms.

Examples

Example 1

$c = Get-Credential

This command gets a credential object and saves it in the $c variable.

When you enter the command, you are prompted for a user name and password. When you enterthe requested information, the cmdlet creates a PSCredential object representing the credentialsof the user and saves it in the $c variable.

You can use the object as input to cmdlets that request user authentication, such as those with aCredential parameter. However, some providers that are installed with PowerShell do not supportthe Credential parameter.

Example 2

$c = Get-Credential -credential User01$c.UsernameUser01

This example creates a credential that includes a user name without a domain name.

The first command gets a credential with the user name User01 and stores it in the $c variable.The second command displays the value of the Username property of the resulting credentialobject.

Example 3

$Credential = $host.ui.PromptForCredential("Need credentials", "Please enter your user name and password.", "", "NetBiosUserName")

This command uses the PromptForCredential method to prompt the user for their user name andpassword. The command saves the resulting credentials in the $Credential variable.

The PromptForCredential method is an alternative to using the Get-Credential cmdlet. When youuse PromptForCredential, you can specify the caption, messages, and user name that appear in theprompt.

For more information, see thePromptForCredentialdocumentation in the SDK.

Example 4

This example demonstrates how to create a credential object identical to the one returned byGet-Credential.

$User = "Domain01\User01"$PWord = Read-Host -Prompt 'Enter a Password' -AsSecureString$Credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $User, $PWord

The first command assigns the username to the $User variable. Ensure the value followsthe "Domain\User" or "ComputerName\User" format.

The second command uses the Read-Host cmdlet to create a secure string from user input. ThePrompt parameter requests user input, and the AsSecureString parameter masks the input andconverts it to a secure string.

The third command uses the New-Object cmdlet to create a PSCredential object from the valuesstored in the $User and $PWord variables.

Example 5

Get-Credential -Message "Credential are required for access to the \\Server1\Scripts file share." -User Server01\PowerUserPowerShell Credential RequestCredential are required for access to the \\Server1\Scripts file share.Password for user Server01\PowerUser:

This command uses the Message and UserName parameters of the Get-Credential cmdlet. Thiscommand format is designed for shared scripts and functions. In this case, the message tells theuser why credentials are needed and gives them confidence that the request is legitimate.

Example 6

Invoke-Command -ComputerName Server01 {Get-Credential Domain01\User02}PowerShell Credential Request : PowerShell Credential RequestWarning: This credential is being requested by a script or application on the SERVER01 remote computer.Enter your credentials only if you trust the remote computer and the application or script requesting it.Enter your credentials.Password for user Domain01\User02: ***************PSComputerName : Server01RunspaceId : 422bdf52-9886-4ada-ab2f-130497c6777fPSShowComputerName : TrueUserName : Domain01\User01Password : System.Security.SecureString

This command gets a credential from the Server01 remote computer. The command uses theInvoke-Command cmdlet to run a Get-Credential command on the remote computer. The output showsthe remote security message that Get-Credential includes in the authentication prompt.

Parameters

-Message

-Title

-UserName

Inputs

Notes

You can use the PSCredential object that Get-Credential creates in cmdlets that request userauthentication, such as those with a Credential parameter.

The Credential parameter is not supported by all providers that are installed with PowerShell.Beginning in PowerShell 3.0, it is supported on select cmdlets, such as the Get-Contentand New-PSDrive cmdlets.
