Xbox One Constantly Logging Me Off

Today I logged on and it was working just fine, but then I downloading the Dragon Teeth DLC from Battlefield 4. And that didn't even work, I had to do a hard restart for it to even say I had the DLC on Battlefield 4. But now, I can't even stay on for over
10 mins without my console randomly logging me off for no reason. Can someone explain why this is happening? It's ridiculous. I even went as far to just do a factory reset.

How to ged rid of this "Add Security" thing?

I keep getting constantly logged off of Xbox Live by Microsoft constantly prompting me to add another phone number of e-mail address for security.

Problem is I only have ONE phone number and ONE e-mail address, so I CANT add another. And i cant figure out how to get to stop freaking popping up and logging me off of Live.

Can someone help me get this to top please?

 

Family account

There was only one gamerpic on the home screen and that one was mine. The xbox was off. He went to school. I turned on the xbox, it logged me in. He was not even in the house. The only pic by the log in was mine. The sceen was my color... there was nothing to indicate his account was logged in at all. Is there another way to tell. The player two controller was even off.....

One another note, how can you tell which controller is logged in under who?
