I came to a friend's house, can I log in to my xbox account from his console?

Yes you can. Just make sure to sign out of it before you leave.

I'm having the same issue with my son's Xbox one. Odd thing is, that he was just over at a friends house, logged into his account from that house and the same problem as at home.

Ok, thank you fo the detailed response. What is the best way to setup the second live memebership? On the console? I believe i was prompted to setup a live account when i did inital setup.

Also are you saying as long as i remember login that i could techically sign into my account from any xbox, it does not have to be on my live account? Ex: i could go to a friends house and log into my account on his console?

I have a friend whose xbox one was stolen from his house. I went online to play and noticed that the person that stolen the Xbox one is playing on my friends account. Is there a way to track down the theif so my friend can get his xbox one back?

I'm sorry I meant to log on as my account... I'm at a friends house and he had his account signed in, please remove this post! Sorry!
