I got a Yubikey a few weeks ago and thought I'd switch to an online bank that offered Yibikey login... I spent hours looking and couldn't find any. Not even one. Couldn't even find any offering Google Authenticator. I saw that a few of the biggest banks will ship you an RSA token/similar device if you ask, but not quite what I had in mind.
