Let me share with you an anecdote from a friend of mine:
Lost my YubiKey around the start of the year and couldn't understand how it could have disappeared so I deregistered it everywhere and went back to Google Authenticator. Found it today [July] embedded in my gravel driveway where it must have been since January and been stepped on/run over since then. Popped it into the computer mostly for fun, and it works like a charm. :P Hardy stuff! :)
