From what I can tell in the docs, the FusionAuth API does not support discoverable WebAuthn passkeys: https://fusionauth.io/docs/apis/webauthn/complete-a-webauthn-passkey-registration#request-body. I wanted to confirm this is accurate as it is not very transparent from the docs, and if there are any plans to add support for this.

I want to implement a passkey login using the WebAuthn API where the user does not need to provide a username/email. I understand there is a "re-authentication" workflow, but that seems designed around the hosted login pages rather than the API. Thanks!

I want to implement a passwordless flow using magic links and email.
https://fusionauth.io/docs/apis/passwordless

If a user initiates the email on device A but clicks the link on device B, is it possible to authenticate the user on both devices using the Passwordless API? I could implement polling or a websocket connection so that device A knows when the magic link has been clicked and can call the passwordless login. But as far as I know, the code is one time use so both device A and device B cannot call the passswordless login using the same code. If device B logs in with the code then device A cannot reuse the code, and vice versa.

Are there known implementations of this flow? Is it wise to log in on one device then share the resulting access token to the other device (via websockets)? Any advice is appreciated, thanks!
