The following example demonstrates how to use a SecureString to secure a user's password for use as a credential to start a new process.

using System;
using System.ComponentModel;
using System.Diagnostics;
using System.Security;

public class Example
{
    public static void Main()
    {
        // Instantiate the secure string.
        SecureString securePwd = new SecureString();
        ConsoleKeyInfo key;

        Console.Write("Enter password: ");
        do {
           key = Console.ReadKey(true);
           
           // Ignore any key out of range.
           if (((int) key.Key) >= 65 && ((int) key.Key <= 90)) {
              // Append the character to the password.
              securePwd.AppendChar(key.KeyChar);
              Console.Write("*");
           }   
        // Exit if Enter key is pressed.
        } while (key.Key != ConsoleKey.Enter);
        Console.WriteLine();
        
        try {
            Process.Start("Notepad.exe", "MyUser", securePwd, "MYDOMAIN");
        }
        catch (Win32Exception e) {
            Console.WriteLine(e.Message);
        }
        finally {
           securePwd.Dispose();
        }
    }
}

Imports System.ComponentModel
Imports System.Diagnostics
Imports System.Security

Public Class Example
    Public Shared Sub Main()
        ' Instantiate the secure string.
        Dim securePwd As New SecureString()
        Dim key As ConsoleKeyInfo
        
        Console.Write("Enter password: ")
        Do
           key = Console.ReadKey(True)

           ' Ignore any key out of range
           If CInt(key.Key) >= 65 And CInt(key.Key <= 90) Then    
              ' Append the character to the password.
              securePwd.AppendChar(key.KeyChar)
              Console.Write("*")
           End If                                    
        ' Exit if Enter key is pressed.
        Loop While key.Key <> ConsoleKey.Enter
        Console.WriteLine()
        
        Try
            Process.Start("Notepad.exe", "MyUser", securePwd, "MYDOMAIN")
        Catch e As Win32Exception
            Console.WriteLine(e.Message)
        Finally
           securePwd.Dispose()
        End Try
    End Sub
End Class
