Password to access WD TV Live files from computer

Hi all. I am able to access my files stored on my WD TV Live media player from my computer. When I access the folder in windows explorer, it does not ask me for a password. I have a tenant who uses my internet connection and so I do not want them to be able to access these files. In the same way that when you click on another computer on your network and it asks you for their username and password, can a password be used on the WD TV Live?


Currently, that option is not available through the settings of the unit.
