WordPress sidebar login widget that allows a user to login, register, or reset their password, ALL without leaving their current location!
Download the WP User Control archive, then extract the wp-user-control directory to your WordPress plugins directory (generally ../wordpress/wp-content/plugins/). Then go to the Plugins page of your WordPress admin console and activate. Once activated, add the WP User Control widget to your sidebar, and configure as desired.
NOTE: The custom login URL setting will affect logins sitewide. Make ABSOLUTELY CERTAIN you are entering a valid URL before saving, or it could cause you problems getting into your site.
