Often met the opportunity on the sites login via email. Today I found how to embed this feature in the site on WordPress. To activate the feature, you can simply paste the following code into the function.php file.

function login_with_email_address($username) {
        $user = get_user_by('email',$username);
        if(!empty($user->user_login))
                $username = $user->user_login;
        return $username;
}
add_action('wp_authenticate','login_with_email_address');
function change_username_wps_text($text){
       if(in_array($GLOBALS['pagenow'], array('wp-login.php'))){
         if ($text == 'Username'){$text = 'Username / Email';}
            }
                return $text;
         }
add_filter( 'gettext', 'change_username_wps_text' );

function login_with_email_address($username) {

$user = get_user_by('email',$username);

if(!empty($user->user_login))

$username = $user->user_login;

return $username;

}

add_action('wp_authenticate','login_with_email_address');

function change_username_wps_text($text){

if(in_array($GLOBALS['pagenow'], array('wp-login.php'))){

if ($text == 'Username'){$text = 'Username / Email';}

}

return $text;

}

add_filter( 'gettext', 'change_username_wps_text' );

Code checked, everything works great. Good luck with development.
