re: fragility of the keys, I can say that I've had a "standard" model
yubikey on my not-insubstantial keyring (a multi-carabiner system on a belt
loop) since 2010 and it has survived a beating, very little worse for wear.
I've had a "neo" model on there for the past year as well, and it's in fine
shape. They are nothing if not durable.

I'm hoping that the firefox gang will integrate support for u2f soon, but
the bugzilla thread about (
https://bugzilla.mozilla.org/show_bug.cgi?id=1065729) is a little
depressing and bad; although in the past week it's started to pick up a bit
and there's now apparently a modest bounty (
of around $900 on the issue available for the taking, which is pretty cool.

I'll second that the documentation availability isn't that great. I like
the idea of the product generally, though, so I'm also kinda hoping that
this github deal will get more people interested and lead to a bit wider
support and better docs.

Mostly I use mine with a password manager with a one-time-password (OTP)
setup (which is a bit different than U2F - and why yubico is creating U2F
to compete with itself it a little beyond me) It also seems silly that I
can't use it as a 2nd factor for all the various services that offer 2nd
factor via text messages, authenticator apps, keychain dongles and whatever
else, but maybe someday soon.
