You should take seriously the advice about using a 2-factor authentification for your own security, even if your account was probably not hacked.
I should, but the only
functional 2-factor security I've seen, involves total disposal of anonymity. I let Coinbase send me txt messages at every login, required for confirmation of every trade or send. But txt messaging my phone when I'm using a mixer, hmmm.... Seems to defeat the concept, eh? ;-)
