Yubikeys have been added as a method of two factor authentication.
Currently supported are standard yubikeys (ordered from Yubico).
We will add support for MtGox Yubikeys once I get the key in the post.
Nefario.
I assume that it is safe to use the same Yubikey then on different sites & the key generates a code that is specific only to that site at that time rather than one that could say also be used to also access Mt. Gox if one had the password too, sry for my lack of knowing the tech for these & thanks for having implemented this - I much prefer Yubikeys to other 2FA as I don't have a smart phone.
