I would sleep better if you added 2 step login verification for security, especially with all the rogue Bitcoin miners around.
To give you an example 2 months ago my Amazon AWS account, in which I had not activated 2 step verification, got hacked, and because I was using Floydhub instead I did not notice and the hacker/jerk had 40 machines running 24/7 for a month and a half for Bitcoin mining. After I received an alert from Amazon I checked my account and I had a debt of 4700 $
Thankfully the whole thing was resolved and I did not have to pay anything, but in retrospective, none of this would have happened if I had activated 2 step verification from the start.
