Seems to miss the point
The point of using WeChat on the home computer is for when it is not convenient to use the mobile phone OR when the mobile device isnt available. So by requiring the mobile device to log in on a desktop or laptop seems to completely miss the point. But in truth, if you do have your mobile handy and can log in by scanning, then it works well. Nice to use a real keyboard.
