Change "Section Name" to "Members Area" or something that makes sense for you.
Create a .htpasswd file somewhere on your webserver (preferably NOT in your web-accessible directory structure).
Update the AuthUserFile line of .htaccess to contain the full path to your new .htpasswd file. If you are using GoDaddy hosting, this full path will be: /home/content/u/s/e/username/html/.. where 'u', ’s’, and 'e' are replaced by the first three letters of your hosting username, and 'username' is replaced by your username.
(for example, if my username was brian, and my .htpasswd file was uploaded to /mynewprotectedarea/.htpasswd, the full path would be /home/content/b/r/i/brian/html/mynewprotectedarea/.htpasswd)
The .htpasswd file needs to contain encrypted username:password pairs for the people that will be allowed to access the protected directory. Visit this page and enter a username & password pair, click 'Create Password', then cut-and-paste the resulting encrypted password line into your .htpasswd file. You will need to repeat this step whenever you add a new username/password account.
That should be it. Try it out and let me know if these instructions need updating.
