I'm less worried about losing a hardware key than I am about something breaking in a mysterious way and locking me out! My initially question was really about personal (unshared) systems. (I don't know - a random auto-update busting a non-standard PAM module and preventing it from loading, or even something just changing the PAM configs on its own, doesn't seem impossible to me). I'd definitely keep a spare if i went the Yubi route.

It's pretty hard to permanently get locked out. In a pinch, you can always mount the disk in another machine, fix whatever is wrong, and boot the original machine back up.

  Or if you rent a server from a provider they usually offer a rescue mode boot option.
