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.

How about creating custom WordPress login page using

<?php wp_login_form( $args ); ?>

Place on the page template the title you wish and the site information then call the login form.

Alternatively(I have not tested this!) adding information in the form area by passing the information you want to add in an array. It will look something like :

<?php

if ( ! is_user_logged_in() ) { // Display WordPress login form:
    $args = array(
        'redirect' => admin_url(), 
        'form_id' => 'loginform-custom',
        'label_title'    => __( 'Site Title' ),//Displayed in the login form
        'label_username' => __( 'Username' ),
        'label_password' => __( 'Password' ),
        'label_remember' => __( 'Remember Me' ),
        'label_log_in'   => __( 'Log In' ),
        'remember' => true
    );
    wp_login_form( $args );
} else { // If logged in:
    wp_loginout( home_url() ); // Display "Log Out" link.
    echo " | ";
    wp_register('', ''); // Display "Site Admin" link.
}
?>
