There have been stories lately of people’s Apple ID accounts being hacked. This includes the selling of people’s Apple ID’s on the “Dark Web”. A major step toward preventing this is setting up 2FA (two-factor authentication) on your Apple ID. 2FA is kind of a pain to deal with, but I don’t see any way around it for security purposes. This article explains how to setup 2FA. I highly recommend you turn it on for your own peace of mind.
