Question: How many profiles can sign in to Xbox Live using Xbox One?
Millions.....a different person every day can come to my house and sign in with their profile, use my machine, and then leave....rinse and repeat for a million days....
Well given they have 300,000 servers I think the answer is 300,000. One each.
The 1st answer from Alex2751 is correct - 6 people can sign in at once on a single console.
The OP never asked how many at ONCE, just how many....so my answer is also correct
Odd that it supports eight control pads but only six can sign in.
