Yes I looked into it, but it looks like WebAuthn does not support multiple devices (let me know if I am wrong).
What if I want to login from two different devices? I don't think that is possible with WebAuthn, but using my authenticator you can login to multiple devices. You will also be able to add a recovery email address to my authenticator to recover your accounts if you phone gets damaged/lost.

This worries me. That means I have to trust you to not leak my 2FA. Authy does this already and so I don’t use Authy. All my 2FA is on my Yubikey.
What if you don't own a physical key?

This is optional. You can choose not to have a recovery email. Just curious though, what do you do if your Yubikey gets stolen/damaged/lost?
