Hi,
Easy Profile does not have any login form, it extends Joomla user management and login is something related to Template, Joomla User component and/or Joomla Login module.
I can see your login only when I make a mistake in the password in the joomla login.
Probably the login popup is generated by Template or a Joomla module (probably it is a Joomla module in a specific position that insert it into the popup), when you insert wrong credentials then Joomla redirect you to Joomla User component.
