- What is
FIDO CERTIFIED™
?
FIDO CERTIFIED
means that implementation has passed FIDO conformance tools, passed interoperability even, and has achieved official FIDO Alliance certification. A registered FIDO Alliance Trademark.
- What is
FIDO CONFORMANT
?
FIDO CONFORMANT
means that implementation has passed FIDO conformance tools (as reported by the author), thus can claim that it is conformant with FIDO2 specifications. If you want to get access to the conformance tools, you can do it here https://fidoalliance.org/certification/functional-certification/conformance/. If you have passed conformance tools, send me a DM or a tweet @herrjemand with a screenshot of passing the tests.
- FIDO2 or WebAuthn?
FIDO2 is the name of the standard. WebAuthn is just browser JS API to talk to the authenticators. So correct way to call your server is "FIDO2 Server" and to say "Authentication with FIDO2".
