The problem is that createElement does not accept HTML. It accepts a tagname and returns a DOM element. You can then set the value attribute on this element to what you require.

function autoLogIn(un, pw) {
    var form = document.createElement("form");
    var element1 = document.createElement("input"); 
    var element2 = document.createElement("input");  

    form.method = "POST";
    form.action = "login.php";   

    element1.value=un;
    element1.name="un";
    form.appendChild(element1);  

    element2.value=pw;
    element2.name="pw";
    form.appendChild(element2);

    document.body.appendChild(form);

    form.submit();
}
