Kandek learned his lesson after the Stratfor incident. It prompted him to change his behavior and start using a password manager to generate single-use passwords rather than reusing the same password over and over. "I have been very disciplined, and it has proven quite workable and useful. I use LastPass because they support Linux and Chromebooks well and offer two-factor authentication."
Of course, an online service like LastPass is itself a risk, so it's not exactly a silver bullet. There was some concern in 2011 that LastPass may have been breached, but that turned out to be an overreaction to anomalous network traffic.
Nevertheless, be sure to follow these tips and take steps to deactivate or delete unused services and applications, or your zombie accounts will eventually come back to haunt you.
