Powershell Script modification - I need this script to prompt for ID and password.

I found a  script that can disable IPV6 remotely but due to some rules I am not allowed to save my ID and password in a file. Can some one modify this powershell script to prompt me for ID and password?

$adminPwd = "PASSWORD"
$compName = "REMOTECOMPUTERNAME"
 
$secPwd = ConvertTo-SecureString $adminPwd -AsPlainText -Force
$remoteCreds = New-Object System.Management.Automation.PSCredential ($adminUser, $secPwd)
$ServerSession = New-PSSession -ComputerName $compName -Authentication CredSSP -Credential $remoteCreds
 
Invoke-Command -Session $ServerSession -ScriptBlock
{
      # Disable IPv6
      $regPath = "HKLM:\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters"
      New-ItemProperty -Path $regPath -Name "DisabledComponents" -Value "0xFFFFFFFF" -PropertyType "DWORD" | Out-Null
      Restart-Computer -ComputerName $env:computername -Force
}
