IT Security. Today is 'new password day' for me - we need to change our login passwords every 70 days, with no repeat of previously used passwords (well, you can, but you have to use dozens before you can repeat). As a result, I've spent all day either entering my old password or getting part-way through entering my old password then starting again with the new one. This also means some other passwords are due to expire. I understand the reasoning behind it all, but it's still a PITA.
