- tialaramex 7y agoThe flag you're talking about is (as its name hints) about the legacy U2F which can't do this flow at all. As I explained this already works fine and I use it every day. Using the FIDO2 Yubikey as sole source of truth replacing usernames and passwords is not available in U2F that's a WebAuthn feature only and apparently it doesn't work in Firefox yet which is disappointing.
