We want all users to enter their employment ID so we can identify them, but it's not so important that we require them to register or remember a password.
Some users will be registered for the service, and they will have to enter a password in order to gain access to further functionality.
What is the best way of explaining to new users that they can just enter their UID without needing to register or use a password? This is what we have come up with, but I'm concerned that these users will get confused and think they need to register.
