Question for strange AuthenticatorTransport ( cable , blank )

[taeseon-lee]

hi.
In my case, some strange case exist.

• On Android & FireFox,
  AuthenticatorTransport return cable, internal

• On iCloud keychain(some few strange case)
  AuthenticatorTransport return blank (means empty string)

Any ideas what is going wrong here?
do you have any plan for this case?
or should i filter those strange AuthenticatorTransport case, and revise to other normal value?

Hi, sorry for the delayed response. This sounds like a question for the browsers, since those values are generated by the browser/platform, not this library.

Note that the behaviour will differ between platforms (Android vs iOS, for example). If your examples are from the same device, then I don't know why you're seeing inconsistent behaviour. One possibility could be if you have some incognito/privacy mode enabled in one case and not the other, as some browsers might not want to share this transports information in that mode.
