As i liked to have fun with hacking i understood one thing - most money you can steal/get not because of guessing passwords or using big hacker skills but just using social skills...you will not believe how easy is to get so many unauthorized things in institutions even like bank,you need only one not "bright" employee and know basic statistics. 99% times human is weakest link.

Just at least print on paper your most important passwords(not only for steem) and delete it from your browser in case your device would be hacked,i know people are lazy so it can help:D even when having' millions they are still can be very naive:).
