    1. Authy is a simple way to manage two-factor authentication accounts. Authy supports Gmail, Dropbox, LastPass and thousands of other sites.
      Authy vs YubiKey opinions
      This alternative is disputed. Authy is still a legitimate alternative to YubiKey, but it might have issues that some users think are important.
      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.

      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.
