I require a password to access my computer, but to top that off, I try not to store any sensetive [sic] data on my computer. Lists of passwords however, I HAVE to store on my computer, and what I do, is I encrypt them. The simplest way to encrypt something is to type it up in word, then take a screenshot of it, and save the PICTURE as an unknown filename, then of course, you put that in a password protected .zip file.

That password protected zip file really isn’t secure, but the sheer inconvenience of this awkward security-through-obscurity method is what makes it so remarkable: a screenshot of a Word document!
