How can I move Confirm Password: (label and input field) down to next line in my register form?

I am using TT login/register form for my multisite. Would like to move a "Confirm Password:" (label and input field) down to the next line in my login form.

It is stuck next to a line of text that makes readability tough: (Leave fields blank for a random password to be generated.)

Is there a way in css?
label password
input password_2

input password_1 is fine

I cannot find it in my register.php or login.php. Are passwords added to forms from an outside source? Are they called something like "meta"?

Thank you.
