Also, don’t forget to remove your account from that website completely using the next method. 

#5 Erase history and cookies

When you are done with your computer work on a public computer the very first thing you need to do is delete history and all the saved cookies.

This is another a bit annoying practice but the most important one to follow.

After you are done downloading the files and taking prints of them whenever you reach home or have free time on your hand just change the password of that account.
