Regarding the comments: they may seem ridiculous after you've been browsing HN and reading the comments on here. The kind of discussion on that Wired article is not any worse than your average Internet discussion, it's just that HN raises your bar because it targets a narrower demographic. Such niche communities tend to have the most sane behavior of users; on the other end is 4chan's Random board where "everything goes", and look at it, it's the asshole of the Internet.
That all said, I'm sure more people will buy into fingerprint passwords from articles like this ... which is just as insecure, someone can easily get your prints if they wanted to. Perhaps we need a bluetooth Yubikey plus manual entry for 2FA ;-)

(It's a case where physical security and physical accessibility come in pretty direct conflict!)
I think the solution given by the article researchers that randomizes the locations of the numbers on the PIN entry is a much more effective solution than wantonly destroying people's property or assaulting them because of a perceived, imaginary threat.
