How Often Should You Change Your Password?
jhigh writes "Bruce Schneier asks the question, how often should you change your password? 'The primary reason to give an authentication credential — not just a password, but any authentication credential — an expiration date is to limit the amount of time a lost, stolen, or forged credential can be used by someone else. If a membership card expires after a year, then if someone steals that card he can at most get a year's worth of benefit out of it. After that, it's useless.' Another reason could be to limit the amount of time an attacker has to crack the password, but Bruce's analysis seems on target."
...lose the post-it note on the bottom of your keyboard that you wrote it on, of course.

Speaking of which, I'm surprised nobody has posted the link to the relevant xkcd yet.
