You can password protect any of your directories to grant only specific users access. In order to password protect a directory within your Plesk control panel:

• Log into your Plesk control panel
• Once logged in, click on the “Home” link from the right hand navigation
• Next, click on the “Protected Directories” icon
• Click on the “Add New Directory” icon
• Enter the directory that you would like to protect (if you enter a directory that does not exist, the directory will be created for you)
• You can choose to have the directory be non-SSL, SLL or both. 
• You can also choose whether or not to have a cgi-bin folder created within the protected directory
• Entering “Header Text” will display a message to the user when they are prompted to log into the protected directory
• Click the “OK” button to create the protected directory

Important Note:If the directory has SSL enabled, it will appear in the protected directories list with a blue lock icon beside it. If it is a non-SSL protected directory, I gold lock icon will appear next to the directory name.

Next you’ll need to create users for your protected directories:

• Choose the protected directory you’d like to create users for by clicking the name of the directory
• Select the “Add New User” icon
• Fill out the form for the user information and click “OK”
