Once WordPress has been installed on your web server, you can access your WordPress login page from two different URLs.
1. Your WordPress Login URL - The first way to access your WordPress Login URL will be in this format: http://yoursite.com/wp-login.php
2. You can also log in from: http://yoursite.com/wp-admin
From your WordPress login screen, you’ll enter the username and password that you set up during the WordPress installation process. If you’ve forgotten your WordPress login password, you can click the “Lost Your password?” link to retrieve it via email.
