Two weeks ago, we talked about password management software like LastPasst to help organize and secure your login and passwords.  We closed our post with a crucial question, what happens if your password manager gets hacked or what happens when a hacker gets a hold of your Master password to access a service like LastPass?  You need to set up two-step authentication on your most important online accounts.  Like your password manager, your social media accounts, your email, and your banking.
