You can easily sign into the WordPress Dashboard. On your browser’s address bar, type in:

www.yoursite.com/wp-admin or www.yoursite.com/wp-login.php

Fill in your WordPress Username(Email address) and admin password. If you had set up your own WordPress then you should have set them up during the installation phase. If Sajah’s Design Studio had set it up for you, you should have received these files in documentation after your project completion.

Once you have logged in, you will be redirected to your Dashboard and from there you can manage it.
