    Any chance of supporting Google Authenticator so people don't need "yet another device" (or MyPW, or YubiKey, or Verisign VIP or Mobile-OTP)?

    Tested with the iPhone OATH generator, and that is fine.

    I don't have an iPhone, and in fact have a proper key-ring gadget as per picture. So no real preference. I tried "OATH Token" and it worked.
