Add text on wordpress admin login page

I want to add a text in admin login page, i searched a lot about this but can't find any thing else a plugin (its my last option).

I also use this filter:

function my_login_logo_url_title() {
    return 'Your Site Name and Info';
}
add_filter( 'login_headertitle', 'my_login_logo_url_title' );

But nothing happen is there any other hook or filter please tell me its urgent.
