title: Mobile Authenticator using CTAP2 specifications
body: <p>I am looking for the use case/scenario for setting up a smart phone as an authenticator using CTAP2 specifications.</p>
  
  <p>I am looking for the use case in which a user setup the browser to interact with their smart phone the same way it would when using Yubikey or another similar security key. I have read all the documentations related to it but unfortunately what I always get an article using Yubikeys / other USB devices as the authenticator. I am looking forward for some interaction where mobile phone serves a  roaming authenticator. </p>
  
  <p>By having a look at the documentation and CTAP specification conceptually I know this can be done by having some connection between the phone and the host via:</p>
  
  <ul>
  <li>Bluetooth</li>
  <li>NFC</li>
  <li>USB </li>
  </ul>
  
  <p>After establishment of connection the mobile authenticator could then implement the CTAP2 protocol so that the browser considers it as roaming authenticator. I am also looking forward to see  the authentication process using some BLE enabled device. I have already tried log-in using yubikey security key on  website. But I want  to achieve the same flow login-mechanism using Bluetooth enable Thetis BLE key  or mobile itself. </p>
  
  <p>Any insights would be very helpful. I am also looking forward for people working on this particular use case to have a mutual discussion.</p>
