I realize this API is relatively new; however, some coding examples would really be helpful: https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API For example, step 2 states, "Browser Calls authenticatorMakeCredential() on Authenticator". How does the browser know what the authenticator is? Specifically, how do you set up an authenticator on a mobile device that will be accessed by a bluetooth call? Is this part of the spec supported yet? Does the developer have to code the bluetooth call to the authenticator? There seems to be lots of general concepts with no specific steps or coding examples. Please help!
