Using Two-Factor (yubikey) with Mac OS X

Outstanding detailed article on using two-factor authentication with the Mac OS X operating system. Note that there is a lot of good follow up in the comments section as well.

I bought a yubikey neo back in October and have been using it with Google’s U2F implementation. I think that this is a smart way to go security-wise and I am glad to see that Google is making it easier to take advantage of. You can also opt for the less expensive yubikey standard if you don’t have a need for the Near Field Communications (NFC) capability on the yubikey.
