To protect a directory in your hosting account with a password, in that directory, create an .htaccess file that contains the following:
AuthUserFile /home/content/
l/
o/
g/
login_name/html/.htpasswd
AuthGroupFile /dev/null
AuthName EnterPassword
AuthType Basic
require valid-user
Where "l," "o," and "g" are the first three letters of your hosting login and "login_name" is your full hosting login. For example, the hosting login "maynard" would translate to the following path:
/home/content/m/a/y/maynard/html/.htpasswd
The AuthUserFile describes where the Web server looks for the .htpasswd file. The .htpasswd file contains a list of users who have access to a protected directory and their hashed passwords. There are a number of tools available online to create .htpasswd files.
