For your specific problem, that server does not require a login.
It uses a random code word sequence, that the user has to remember
to get back on into his project(s).
Your student would have to export his project as an .aia file at the end of every session,
in case he can't get back into that session and has to
import his project into a new session.
I have no information on how long a session remains live
after the user leaves, so I would not use it without a
safe place for .aia export/import, like a thumb drive.
