#2 Add Log In/Out link to nav menu

Simply add this code to your parent or child themes functions.php file to display a Log In/Out link in the secondary navigation menu of the Twenty Fourteen default theme for WordPress.

add_filter( 'wp_nav_menu_secondary_items','wpdocs_loginout_menu_link' );

/**
 * Append Login In/Out link to menu with a redirect to this page
 */
function wpdocs_loginout_menu_link( $menu ) {

	$loginout = wp_loginout( $_SERVER['REQUEST_URI'], false );
	$menu .= $loginout;

	return $menu;
}

Other themes like Twenty Thirteen may require you to add a class to the code like this example.

$loginout = sprintf( '<li class="nav-menu" class="menu-item">%s</li>',
	wp_loginout( $_SERVER['REQUEST_URI'], false )
);
