Re: [webauthn] How do I use a smart phone as an authenticator when the web application is running on a laptop/desktop? (#954)

Hi @CalldiDoctor, I wrote webauthn.io. I would imagine they're using some version of CaBLE in order to create the connection to the phone, rather than handling the phone outright as a bluetooth authenticator. Currently, webauthn.io looks for usb, nfc, and ble transports, if asked for cross-platform authenticators.

> I do not know how the roaming authenticator (my phone) will listen to the calls from the browser, in order to generate the key pair or sign challenges.

I would check out how [Krypt](https://github.com/kryptco/kr-u2f) handles overriding webauthn/u2f requests and sends them to a mobile device.
