Yes, you can password protect any directories and files placed within them. To do that, please follow these steps:

• Login into your cPanel and click on the "Password Protect Directories" icon, under "Security section" of cPanel.
• From a list of the directories select the name of the directory you wish to limit access to.
• On the new page, please create a username and password. Just fill in the username and password (at least 6 characters long) for the username.
• Next, check the box next to "Password protect this directory";
• Write a warning message in the "name the protected directory" filed. This is the message that will be shown when someone tries to login in the protected directory.
• Click on save button below.

Congratulations, the directory you selected is now protected by a password!
