I'm currently finishing development of FIDO2-conformant authenticator and we're looking to certify it in close future.
It already passes through everything inside 1.52 conformance tools. However, I'm interested in supporting features inside upcoming FIDO2.1 standard. What's the right approach? As far as I can as see, all of the mandatory features in upcoming standard are doable through firmware update. If I certify it according to FIDO2.0, do I need to certify(pay) it again for newer standard?
And what about metadata statements, are they updatable when the authenticator starts supporting more features?

Best regards,
Roman Došek

Hello Roman,


Updating an authenticator from CTAP 2.0 to 2.1 will require recertification as define here - This type of upgrade will require at least a Delta certification.

As someone currently doing CTAP2.1 certification.  The change is big enough that we are doing a new certification from scratch and changing the AAGUID so it will have a new entry.  

Updating the MDS for minor changes is fine, but MDS3 contains the contents of getInfo so a CTAP2.0 and CTAP2.1 sharing the same entry is probably not ideal.  

I feel for you on cost, so file a FIAR and see if you can get away with a delta.   It just wasn't worth the time for us to bother with that. 

You can find the CTAP2.1 test tool in the experimental directory of the test tool.
