At school i have a similar system like that, we have to change our password every 2 weeks, this is a website were we send our works and exams, if we dont login in 2 weeks, and happens quite often since we dont have exams our works to send every 2 weeks, we dont need to change our password, but if we do, the first time we login after we change the password 2 weeks later weneed to change it again, plus we have to use a password with at least 20 caracters, thats why i use a program called keypass, i can generate diferent and strong passwords, save them and reduce the risk of happening the same that happen to that sm,org admin.
Another way but i think it can get a little anoying is the system that steampowered.com uses with user accounts, asks for a small code when we change computer or ip address.
