More than one password :

If you want to have more than one password, modify script in this way :
ADD new condition If (OutString == "new_number")

Original script, added new condition

  if (OutString == "10009804" )
    {
  window.open ( newlocation, "_new", "resizable=1, toolbar=0, location=0, menubar=0, status=0");
    }
    else
    {
     if (OutString == "new_number")
       {
     window.open ( newlocation, "_new", "resizable=1, toolbar=0, location=0, menubar=0, status=0");
       }
       else

       {
    alert("ACCESS DENIED");
       }
    }

Each opened "{" must be close with "}" ... so count it carefuly !
