I highly recommend enabling the two factor authentication feature. I got my account targeted by some botnet and was breached several times regardless of how ridiculous my password was. Of course, this all stopped the moment I started using two factor auth.

I've got some Chinese IP trying to log in to my account every 4 or 5 days at the moment it seems. Prior to that, it was a Japanese IP every few days for a couple of weeks.

Two factor auth. via my mobile is great.

This was my experience as well. I did not know 2-factor was offered by MS. Definitely using that now!
