You probably visit the login page on your WordPress-powered website at least once a week; perhaps one a day. Although WordPress does not include any options to customize the login page to suit your needs or preferences, there are plenty of tutorials and plugins floating around.

This is useful if you want to help prevent users from loosing their password or provide special options to logged-in users (i.e. a no ad version of your site).
