In these days people tend to have lots and lots of passwords. Though things like Mac OS X's keychain and KDE's wallet system are great ways to keep track of these things, have you ever considered the other part of computer security? Your hardware. So it's great that you have the 64 character password but what do you do when your entire computer gets stolen? Mac OS X has a great system called FileVault that encrypts your entire home directory and to my knowledge there is no way to hack it. But that just isn't enough for me.
After watching a few episodes of the Discovery Channel's "It Takes a Thief" I realized how valuable my computer is to me. Not even considering the possibility of identity theft, computers are expensive and some of us are even too cheap to buy the school apartment insurance. Instead I recommend just using a good lock and cable to secure your machines. Whether laptop or desktop they are equally easy to steal.
fileVault is slow. So slow it feels like you're using a PC!
but seriously, my final cut scratch folder was in my home folder by default. You can imagine how much fun it was to en/decrypt that on the fly!
It's unfortunate that we are too lost in the idea that digital security is way more important than physical security, and we completely forget about securing our computers. Although a theft of the actual machine is less likely than a hacking attempt, it could reveal much more than a hacker could ever obtain.
It's even worse when people give away or sell their computers with all this information: http://news.bbc.co.uk/1/hi/technology/4229550.stm
