Fine-tuning of ceremonies

Support for mobile devices as cross platform authenticators

Nevis FIDO2 relies on the WebAuthn specification, which defines how the client-side of the protocol must behave. This is then implemented by the different browsers that support WebAuthn, which introduce nuances to the protocol. One such a nuance is caBLE, which is a technology that makes it possible for end-users to use their mobile devices as cross platform authenticators for WebAuthn ceremonies. In this use-case a WebAuthn ceremony is executed on a desktop or laptop, then the authentication takes place on a mobile device through an ad-hoc bluetooth connection, where the authenticator (for example fingerprint scanner) is already enrolled. Note, that this technology is not yet supported by all browsers:
