How to implement a greeting after user authorization in an online store on bitrix?

Question

1C-Bitrix

Hello. I know that the question may require a voluminous answer. But at least in a thesis or conceptual way.
There is an online store on bitrix. It is necessary that ordinary users, after authorization, see the standard Bitrix greeting, if there is one. If not, what is the best way to implement it yourself?

Answer 1

<?
global $USER;
if ($USER->IsAuthorized()) echo "Вы авторизованы! Здрасти!";
?>
