If you know your username and the email account in your profile, you can use the “lost password” feature of WordPress.
- Go to your WordPress Login page (something like http://yoursite.com/wordpress/wp-login.php)
- Click on lost password
- You will be taken to a page to put in some details. Enter your user name and the email address on file for that account.
- Wait happily as your new password is emailed to you.
- Once you get your new password, login and change it to something you can remember on your profile page.
