您可以使用wordpressnodes 自定义配置文件菜单。

Add this in functions.php

add_action( \'admin_bar_menu\', \'remove_my_account\', 999 );
function remove_my_account( $wp_admin_bar ) {
   $wp_admin_bar->remove_node( \'my-account\' );
}

add_action( \'admin_bar_menu\', \'add_logout\', 999 );
function add_logout( $wp_admin_bar ) {
   $args = array(
      \'id\'     => \'logout\',           // id of the existing child node (New > Post)
      \'title\'  => \'Logout\',           // alter the title of existing node
      \'parent\' => \'top-secondary\',    // set parent
  );
  $wp_admin_bar->add_node( $args );
}
