Xbox One Slim Sign In

I've had my Xbox Slim for almost 24hrs.

I've yet been able to sign in. Yesterday before work, I sat at my desk for 5 hrs trying to sign in. I'll hit sign in and it just keeps taking me back to " who are you " add your account to sign in I'll click it, it loads for a few seconds and keeps shooting
me to this screen. I've been sitting here clicking it for like 3 hrs. I just wanna play my new Xbox.

:)

 

Need help setting up two consoles.

I had to set up a 2nd gamertag for my wife because she was signing into the xbox one slim and it was kicking me out of my X.

 

Xbox One and Kinect 2's exact size, cable length revealed

Of course it is quite a bit bigger than the 360 slim, the original Xbox 360 was bigger than the slim, I'm sure it's bigger than the Xbox One slim will be too. That's the point of releasing the slim versions later on. But it is only 2.4cm longer than the original Xbox 360, which is what it should be compared to, not the revised, shrunk later released versions.

Original 360 dimensions

309mm x 258mm x 83mm

Not much in it really.

 

Hello , Have you tried goin to settings -> All settings
-> Delete accounts (and delete account if its there and then try again to add it) .

Second Solution is to reset your Microsoft password.
