Firstly, you will need to know the full path to your document root.
Then, in the directory you want to protect with HTTP authentication, create or upload a file named: .htaccess (remember to include the "." before the "htaccess"). Alternatively you can upload a text file called htaccess.txt and rename this once it has been uploaded to .htaccess
The .htaccess file should contain the following 4 lines:
AuthType Basic
AuthName "Some Description"
AuthUserFile /[home dir full path]/httpdocs/.htpasswd
Require valid-user
For example, if your domain was example.com, then the third line would read:
AuthUserFile /usr/local/www/vhosts/example.com/httpdocs/.htpasswd
Good Luck !!!
