How do you enter the ADDS credentials using powershell.

Before I used

-Credential (Get-Credential)

I want to enter Username and Password using powershell:

-Credential $PSCredential

How do you enter username and password using the same script: $PSCredential?

This is what I have so far:

$Username  = "Administrator"
$SecurePassword  = convertto-securestring "PaSsWorD$" -asplaintext -force
$credentials = New-Object System.Management.Automation.PSCredential -ArgumentList $Username, $SecurePassword
Install-ADDSForest `
...
-Credential $credentials
...

Is it something like this you are looking for:

$secpasswd = ConvertTo-SecureString "PlainTextPassword" -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ("username", $secpasswd)

Hi Philosophiae
$password = "XXXXXX" | ConvertTo-SecureString -asPlainText -Force
$username = "XXXXXX"
 $credential = New-Object System.Management.Automation.PSCredential($username,$password)

or you can use 

$username = read-host "Please enter your name:"
$password = read-host "Enter a Password:" -assecurestring
$credential = New-Object System.Management.Automation.PSCredential($username,$password)
