Thanks for the suggestion. This is the same approach used by many
pastebins which don't have a public index. For my use case I'd
like to make sure anyone who has clicked an invitation link has
access to the entire wiki. I could include a random string in my wiki
root path, but this has some shortcomings:
(1) The URLs are longer and uglier than they need to be.
(2) If members share links to wiki pages with eachother, they are also
sharing the invitation token. I'm not going for high security, but it
makes it feel much less private.
(3) It might be nice to decouple the invitation token from the
authentication token stored in the cookie. Then you could disable
an invitation link after some time, without requiring everyone to
click a new invitation link.
Maybe just using PmWiki's standard password authentication with a

overhead if you have to decide on a password and people have to

links with other services, so it felt like the most natural way to
