Power bi rest api double factor authentication through code across domains

[mivar99]

Hi all

We have a case where we need to connect to power bi rest api through code on other domains with users login and then let them navigate a power bi model. 

But the app needs to support 2 factor authentication

We have a working app now that connects to the rest api for a certain client where users login but only works without 2 factor

We tried searching for answers and found some articles about needing to register an app in cloud to get access token - but that all sounds like its an app within your domain to access power bi rest api in your own domain

Anyone tried connecting to rest api with code and 2 factor authentication across domains yet ?
