How to implement magic link login across devices

[njanaskie]

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!

@njanaskie You are correct in that magic links are designed to be a one time use. I do not know of any work around for your situation.

It will be interesting to see if others chime in.
