There are two methods that you can use to login to your Site Manager account:
If your domain is up and running with your FaithWebsites site, then you can simply enter your domain followed by "/admin", like this:
If your domain is not setup (your website is not live), your account resides on a temporary, or FaithWebsites domain. To login, enter yourtemporarydomain.cmstemp.com/admin
Once you enter your admin URL in your browser, you'll see a login screen (below). Enter your username and password, click LOGIN and you'll be in Site Manager! Enjoy creating your website!
