If you've gone to log in to your WordPress admin area and can't remember your password, don't worry - it's quick and easy to reset.
If you're on your admin login page, simply click the "Lost Your Password?" link
Alternatively, you can go directly to yoursite.com/wp-login.PHP?action=lostpassword (change yoursite.com to your domain name).
Once on the password reset page, enter your email address, or your username and click on the "Get New Password" button.
You will receive an email to the email address associated with your WordPress admin account. The email will contain a link, when clicked it will allow you to enter a new password for your account.
Once complete, you can now access your WordPress admin area via the login page.
