Password protection is enabled via the .htaccess file. If there is no .htaccess file already in the folder you wish to protect, one will be created for you.
It is suggested that you backup your .htaccess file beforehand. You may then edit the file and append your original text to the .htaccess file after it is overwritten. You may also edit your existing .htaccess file manually to enable password protection on the folder if you are familiar with the process rather than following the steps below.
To choose an existing directory, select it from the drop-down box as show in the picture below.
To create a new directory, select the Create new directory radio button and type the folder name into the text box. When complete, click the Save button.
Repeat as necessary if you wish to give the user access to multiple folders.
