If you needed access you'd have to ask someone with the password to turn it off for your computer. That was annoying so we installed key loggers to get the password for ourselves. One of my friends ended up buying a hardware key logger that was even easier than trying to bypass the install protection software they used. Sometimes we'd leave the logger on all day just to see what we'd get. There were lots of email and AIM logins.
