There are two different issues here.

Issue 1: Performance. Wrapping Admin Center in Electron will not automatically make things faster. Memory usage would go up and performance would likely not benefit. In terms of React, Admin Center uses Angular and moving to React would require a substantial rewrite of all the UI code. In short, we understand there's work to do to improve performance and it's underway.

Issue 2: Smart Card/Windows Hello/OAuth Token support. Yes, we are keenly aware of this request and are investigating solutions. Wrapping the app in Electron marginally eases auth in some scenarios while making critical production scenarios (Admin Center in gateway mode) far more challenging. In short, we know this feature is important and it is on the list.
