The password input tag is in a div like this
<div id="passwordCell" style="display:inline;">
<input type="password" pattern="[0-9]*" name="Password" id="Password" placeholder="4 digit numeric only allowed" maxlength="4"/>
</div>
- add another input field in the
#passwordCell
div, and give it an id, for example, password_mask - hide the #Password input field
