A little security goes a long way
With security software, it's easy to go overboard. You could create a small KeePass database, steganographically embed it in an MP3 file, put that file into a TrueCrypt volume, and then launch Tor and tell your friends all about it on Cryptocat. That might be a fun experiment, but in reality, it takes just a handful of best practices to significantly bolster security. If this article makes you do just one thing, I hope it gets you to adopt KeePass and take password security more seriously. And if you're already using a password manager, well, there's always more you can do to further protect your privacy and reduce the risks that come with constantly being online.
