By default, you can access the Wordpress admin panel by visiting: www.mywebsite.com/admin or www.mywebsite.com/wp-admin 

If your website was built by Chrisorah the URL likely differs from the WordPress default URL. This is done to help protect your admin panel from bots and automated attacks. Please contact us and we will provide you with your Wordpress Admin Panel URL.

You should change "www.mywebsite.com" to your actual domain name without the quotes.
