Usage of WFAInputPassword

mszafran — Thu, 05 Jun 2025 04:29:27 GMT

Hi,

I'm trying to use WFA to call the VSC commandlets in VSC 6.0. I have a question on how to pass a password. When I try to grab the password from the input and use it, i get various errors. I tried Get-WFAInputPassword but I get the below error. Can anyone help with a code sample?

Thanks

Mike

Mike,

Some points here:

You need to declare parameter $vcsPass of type Password in your command. See example in WFA developer's guide on how to use it.

2. $passwordp = Get-WfaInputPassword -EncryptedPassword $vcsPass

This itself returns the $password in SecureString format and hence you do not need the line: $password = ConvertTo-SecureString -AsPlainText -Force $passwordp

Just use the $passwordp to create your credential object : $creds = New-Object System.Management.Automation.PSCredential $vscUser, $passwordp

Sinhaa,

Thanks for the reply. I've been trying different combinations with various error messages. Using the Get-WfaInputPassword -EncryptedPassword $vcsPass_Password still produces errors. The $vscPass is now an encrypted string but not one the PSCredential likes.

My parameter:

[parameter(Mandatory=$true, HelpMessage="Specify an VSC password.")]
[Alias("vscPass_Password")] [string]$vscPass,

import-module VSC
Get-WFALogger -Info -message ("Username " + $vscUser)
Get-WFALogger -Info -message (" Password: " + $vscPass)

$creds = New-Object System.Management.Automation.PSCredential $vscUser, $vscPass
Connect-VSCserver $VSCHost -Credential $creds

The correct code should be:

====

[parameter(Mandatory=$true, HelpMessage="Specify an VSC password.")]
[Alias("vscPass_Password")] [string]$vscPass,

import-module VSC
Get-WFALogger -Info -message ("Username " + $vscUser)
Get-WFALogger -Info -message (" Password: " + $vscPass)

#Get the password in Secure String format.

$vcsPass_Sec= Get-WfaInputPassword -EncryptedPassword $vcsPass

$creds = New-Object System.Management.Automation.PSCredential $vscUser, $vscPass_Sec
Connect-VSCserver $VSCHost -Credential $creds
