Is there a way to prevent the LastPass browser extension from filling out a HTML-based form with an input field with the name "username"?
This is an hidden field, so I don't want any software to use this field for their purposes:
<input type="text" name="username" id="checkusername" maxlength="9" value="1999" class="longinput" style="display:none">
The solution should not be like "rename the input field".
Adding
data-lpignore="true"
to an input field disabled the grey LastPass [...] box for me.
