Disable autocomplete for all sensitive fields
For each sensitive field in the HTML, set the "autocomplete" attribute to "off". For example:
<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>
