Similar case here. One of the Google accounts I have has three 2FA setups: SMS, TOTP, and Yubikey. One time I tried logging in I didn't have my Yubikey with me.

Similar case here. One of the Google accounts I have has three 2FA setups: SMS, TOTP, and Yubikey. One time I tried logging in I didn't have my Yubikey with me. I thought no problem I'll use the TOTP authenticator app. Google told me I can't login even though the code was correct. There wasn't any way to address that except by actually using the Yubikey to log in. I'm using a fresh install of Chrome with no addons.
