                        </div>

Solution:

Disable autocomplete for all sensitive fields like: 

<input type="password" autocomplete="off" name="pw">

If there are many fields, it may be faster to set the "autocomplete" attribute to "off" in the outer <form> tag. For
example:

<form action="/login.jsp" autocomplete="off" name="pw">
<input type="password" name="pw">
</form>
