Reset password widget customization

I use universal login in my app.
And I try to customize Log in, Reset Password pages.
On log in page I have a success, and reset password too, but I can not understand how to customize reset password WIDGET…

I can see HTML, CSS code for customizing page outside widget, but how can I change HTML code inside this widget ? (For example for changing texts, or to add third input field)

Thanks!
