It is important that you and only you know what your password is in order to maintain secure systems. Using another person's account is forbidden in the Regulations, and we take steps against those who do.
If someone learns your password, they can log in as you and cost you a lot of money in web traffic and printing. This has happened before and will happen again - don't be the next victim, because you have no recourse. You will pay the costs.
If we have broken your password and deemed it unsafe, then anybody with a PC at home can do the same. How many of your classmates have computers at home? How many of them would you trust with your money, if they knew they could spend it without anybody finding out it was them?
All lab users can change their passwords here.
NOTE:Your Waikato (University wide) password should also be changed. This can be done here.
