USB-Dongle Authentication List
Does the Google Authenticator app count as Two Factor Authentication? Does TOTP count as OTP?

Good question. Yubikeys only support HOTP because of the lack of battery, so I'm guessing they are referring to HOTP. Google Authenticator is TOTP.

I believe a NFC Yubikey paired with a smartphone app (

) supports TOTP by using the smartphone's clock.

With external software providing the clock, you can use TOTP. I use

on my mac with a yubikey for TOTP apps that don't yet support U2F.
