they have the concept of guest account.

enabling the guest account allows users without accounts to log in and
become the guest, even without a password.  a bit like "map username" but
on a smaller scale.

adding a password to the guest account requires that anyone can log in as
any username but they must know the guest password.  they become guest,
regardless of username they type in.
