There are two ways to log into WordPress.
Direct URL
The first way is to type in the name of your website, followed by admin. It will redirect to the login URL similar to the one pictured below.
Then, to log in, you will need to enter the admin username and password you created when originally making the website.
Through Knight Domains Dashboard
The second way is to navigate to knight.domains. There, you will press log in using your SNC email.
From there, it will automatically take you to your dashboard of Knight Domains. Here, you can click My Apps
From there you click on the second link of the website that you would like to edit. This will take you to the WordPress dashboard editor for that site.
