Who else wants QR logins on Xbox One

So they've announced the xbox one kinect will be able to read QR codes for redeeming prepaid cards and I was thinking what if they allowed you to login to a new console via a code on your phone. It would be nice for initial setup but really useful if you go to a friends house. Imagine not needing to tell them to look away from the screen while you spend two minutes typing in your password on the clumsy on-screen keyboard. Microsoft could pretty easily add the functionality to their existing authenticator app or even smartglass. Just tap "login to new console", type in your password or a pin, and it generates a one-time use code for the the Kinect to scan. It would make the whole process faster and actually more secure since you wouldn't be typing in your password on a huge screen where anyone in the room can see it.
