Hmm, never had a theme break because I added dispay: none to login link in admin bar – what broke in your theme?

Another way is to add this in your bp-custom.php

function remove_login_link() {

remove_action( 'bp_adminbar_menus', 'bp_adminbar_login_menu', 2 );

}

add_action( 'bp_adminbar_menus', 'remove_login_link', 2 );
