To login to your WordPress website you had to type /wp-admin or /wp-login.php behind the domain url. Not so easy to remember if you don’t do this daily. But did you know you can also type /admin or /login or /dashboard? These shortcuts were introduced in WordPress version 3.4.
A tip for the more technically minded: if you install the widget Php Text Widget you can place a login form in your sidebar by putting the code <?php wp_login_form(); ?> in a text widget.
