In live.com and related services that use the same account I've been receiving the message
It looks like someone else might be using your account
Now, this has happened to me before in other services like Gmail, because I have several computers and usually log in from different places. In Gmail I can check the session log to verify the IP addresses and locations of the previous sessions so that I know its a false alarm or not.
Does live.com provide such functionality?
If so, how can I access it?
