Ever find yourself with too many passwords to remember and no idea where to keep them so that only you can find the password list? Creating a password.txt file in your root directory is out of the question, as is a password-protected OpenOffice.org file. A piece of paper hidden somewhere is not a good idea, because after you forget where did you put it, someone else will find it and abuse it. Instead of these approaches, consider using steganography, a method for hiding sensitive information inside some other object, typically a JPEG picture or a sound file.
