CTAP2 API from Browser

[J B]

Hi all, I'm trying to better understand how CTAP2 commands are issued from a web browser like Chrome to a FIDO2 authenticator. I see WebAuthn API being referenced a lot in server implementations but this seems to abstract the CTAP2 commands one level higher than I want.

For example, let's say I wanted to build a WebApp to test FIDO2 devices by issuing arbitrary CTAP2 commands. Or if I wanted a tool to just reset an existing device using the authenticatorReset command. Would this be possible?

This looks like it's a c library for FIDO2. How would one make calls to this from a web browser?

It has a commandline tool.  Use that, there is also a python version.    You can’t do what you want from a browser without significant work rewriting the browser.
