Nit: It might be nice to define constants for these values:

constexpr int8_t ATset = 0b01000000;
... etc...

> Source/WebKit/UIProcess/WebAuthentication/Virtual/VirtualAuthenticatorUtils.mm:45
> +        flags = flags | 0b00000100;

Then you could explain what this one means :-)

> Source/WebKit/UIProcess/WebAuthentication/Virtual/VirtualCredential.h:39
> +    bool isVerificationRequired;

Nit: Putting the bools together at the end of the struct can allow better packing of the structure and reduce memory use.

> Source/WebKit/UIProcess/WebAuthentication/Virtual/VirtualHidConnection.cpp:230
> +            Vector<uint8_t> buffer;

Is buffer ever large enough that it's worth hinting the size of the buffer before appending using the 'reserveCapacity' method?

buffer.reserveCapacity(payload.size() + 1)

Scanning through the code, there might be a number of places in the WebAuthn code where this could be helpful.
