I work in an environment where radios and cameras of any kind aren't allowed (not an unreasonable policy for where I work). So, I'll be stuck with the fobs for a bit. The trend of everything moving towards smartphones limits my options. However, YubiKey OTP works well, so it's not a big issue -- I just hope more competition pops up. Also, personally I trust fobs more than my smartphone. My smartphone is a device which is always connected to a network. I don't want to be one remote exploit and a password leak away from having every credential I control compromised.
