I use this time management software at work that forces me to reset my password pretty much every time I open it. What I'd like to know; why does this software require such stringent security. Who wants to hack into my time-sheet and see how many hours I worked on some boring project. I also have one password to login to my laptop offline, one to login when it's online and another to login to work mail as these three passwords are always out of sync. Very annoying.
