If valid password is entered output is:- "Invalid password. Please enter again."

Please advise me the error in this program?


// Program asks user to enter password
// If password is not "home", "lady" or "mouse"
// the user must re-enter the password
using System;
public class DebugFive2
{

public static void Main()
{
const string pass1 = "home";
const string pass2 = "lady";
const string pass3 = "mouse";
string password;

Console.Write("Please enter your password ");
password = Console.ReadLine();

while (password != pass1 || password != pass2 || password != pass3)
{
Console.WriteLine("Invalid password. Please enter again. ");
password = Console.ReadLine();
}
Console.WriteLine("Valid password");
