I highly recommend the above advice. 2-factor auth is a simple step that hugely increases security. You must have it on your email at minimum - since having access to your email typically gives you access to many accounts connected to your email - and probably most of your financial accounts.

I might also encourage Coinbase to limit the maximum dollar value of transfer from an account to, say, $100 per day until someone enables two-factor auth. Typically people have very poor security habits, and strongly encouraging them to improve them will help both users and Coinbase's reputation.
