Passwords

You should change your password at least every 90 days. Dude, do you know how much of a pain that is? My last job I had for a little over six years. For about four of those years I had the same password. The last two years I was there we had a mandatory password change every 90 days. After 90 days when you logged onto any computer the network it wouldn't let you continue unless you changed your password. And get this... you couldn't use previous passwords! All of this is a really good idea, but very annoying. After a few months of coming up with new passwords, I finally just started adding a sequential alphabetical letter. I wonder how many other people do that.
