Are you using fido with "u2f" set?

github issue.

I posted to “github”, but no matter how much u2f is set, the fido device does not recognize it when registering as a user. (No popup window is displayed)

Is there anyone who can use u2f?

If u2f is available, what is the physical key (such as Yubico4) and environment?

Hi,

I am using hardware yubi keys, and its working great. (through web and through linux cli).
My u2f section looks like this:

  authentication:
    type: local
    second_factor: u2f
    u2f:
            app_id: https://teleport-proxy-url
            facets:
            - https://teleport-proxy-url:3080
