CTAP2 Platform Host

Overview#

CTAP2 Platform Host (also called the host in the CTAP2 spec) is the Web Authentication API (WebAuthn Client) part of the Client Device that negotiates with authenticators.

CTAP2 Platform Host is responsible for securely reporting the origin of the request and for calling the CTAP2 CBOR APIs.

In cases where the CTAP2 Platform Host is not CTAP2-aware, the Client Devices themselves MUST take on more of the burden.
