This is a blanket solution that will help you hide the admin bar for everyone, and save time with having to provide the “hide toolbar” info to all users. Handy when working with fixed navigation that will get bumped around in different viewport sizes by the admin bar CSS.
add_action('get_header', 'remove_admin_login_header');
function remove_admin_login_header() {
remove_action('wp_head', '_admin_bar_bump_cb');
}
