The wx/net server may be set up in secure mode, which requires
connecting clients to supply passwords in a manner similar to a Unix login. In addition to
passwords, each user may have a maximum login number and class of service assigned to
them. The former controls how many clients a particular user id may have connected at
once, whereas the latter permits selective access to various services for a given user
(e.g. real-time data might be permitted but chat services are blocked). This gives the
administrator control over who may use what resources the wx/net server has to offer.
Passwords are encrypted at both the server and client end, and the transmission of the
password over the network is encrypted again using a random key value selected at login
time. This prevents easy viewing of users' passwords in data network traffic.
Administrators may reset user passwords but they cannot see what they are nor decipher
them, thus protecting users' privacy. The system is not guaranteed to be foolproof, but it
should be adequate for the intended usage.
