How to disable login by name in wordpress?

Question

User identification

I can’t really find how to make it so that the user can enter the Wordpress CMS only by email. To not use a username. Since the name is visible on the main page where the posts are, and it is not difficult to see this name.

Hello!
There is another way:

/*
 * Сокрытие админского логина
 */
function hide_login_in_name($author) {

  if ( strstr($author, "Test") ) {
    return "Test2";
  }
  return $author;

}

add_filter('get_comment_author', 'hide_login_in_name');

Test - real name Test2
- what will be displayed instead
