    This is the only option listed that is actually a hardware token like Yubikey and also has a critical mass of users and support. Open Source is a plus also.

    Authy is a two-factor authentication app, while YubiKey (and other U2F devices) is a two-factor hardware token.

    Software OTP generators are not the same as hardware ones. The hardware ones are more secure because a newbie might use SMS for 2FA, which means that for apps on their phone, the 2FA is useless. A hardware token like Yubikey keeps the token and the app separate since no apps can run on the Yubikey.
