If you don’t have two-factor authentication (2FA) turned on for social media (much less your financial accounts and email), I hope elves visit you in the night and pluck your nose hairs with tweezers. If you don’t know what 2FA is and you’re using the internet for anything, you’re probably not going to like me telling you that you’re almost certainly giving away all your entire identity. 2FA isn’t perfect – but it is the minimum standard for anything you value.
