Hi @min.soo.kim,
Welcome to the Auth0 Community!
You should be able to use most SDKs to get a passwordless magic link set up. The SDKs initiate the request and handle the response in the client, regardless of which login method you are using.
The passwordless setup part happens on the Auth0 server.
This doc demonstrates how to set up passwordless.
And this doc shows how to get a refresh token, although much of the code here will be handled by the SDK. Do you know which SDK you would like to use?
