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.

- cesarb 11y agoI believe a NFC Yubikey paired with a smartphone app (https://play.google.com/store/apps/details?id=com.yubico.yubioath https://play.google.com/store/apps/details?id=com.yubico.yub...) supports TOTP by using the smartphone's clock.
- mcpherrinm 11y agoWith external software providing the clock, you can use TOTP. I use https://github.com/zeteticllc/onetime https://github.com/zeteticllc/onetime on my mac with a yubikey for TOTP apps that don't yet support U2F.
