Well that was amazingly useful. Someone had guessed my PW and was logging in regularly from a Windows CE device in Denver.
Very odd and confusing. Scary since my Skydrive has all sorts of personal stuff in it.
2 factor is awesome, but I always fear losing access to my account. Basically it means that if I don't have my smartphone on me, I have no way to check my email except on pre-authorized computers.
This is of course the point but it also means if I am traveling and I lose my smartphone, I have no way of contacting anyone that I know. I would be completely lost in the world and unable to reach out to anyone for help.
Of course there is the recovery code, which I have a copy of in my wallet, but that does me no good in a "traveling through city, get mugged" scenario.
It is scary how reliant we are upon technology. :(
