How is U2F considered legacy already? It's still fairly the most modern way for a 2nd factor. WebAuthn just came outmonths ag and most of the Yubikeys - as well

How is U2F considered legacy already? It's still fairly the most modern way for a 2nd factor. WebAuthn just came outmonths ag and most of the Yubikeys - as well as apps/sites/services -- don't support it.

Yes, they do. WebAuthn is the modern API, but it’s backwarss compatible with every U2F device. You don’t need a WebAuthn key to use the WebAuthn API.

  Gotcha. I guess I was thinking about the new FIDO standard on the new Yubis.
