Of course, installing your token permanently (as shown in the article)
kind of defeats the purpose, since the idea of two factor authentication
is "something you know" (the PIN/password) and "something you *have*"
(the token). If you don't keep physical possession of the token, that's
a big problem.
In fact, the article is all about getting around having the human
there.. the PIN is entered by his software and his software reads the
token. So anyone who has access to his computer has access to his
identity. And I'll bet his computer is connected to the internet, so
that means *everyone* has access to whatever is secured by his token.
(after all he is doing it so he can get access to his work VPN).
Probably a good reason not to use NetArt Group s.r.o. in the Czech
republic (his employer) if you care about security.
I suppose, though, there are places that are more casual. After all,
there's that guy who outsourced his work to China and mailed the guy in
China his token.
