Remove Header on Password Page 'Origin' Theme

[IronWisdom]

How can I remove the header only on the password page of the 'Origin' theme?

Share the URL of the page. It can probably be done with CSS. 

.header-class-goes-here {
display: none;
}

Would just need to look at the page's coding, to see if there's an appropriate class to use.
