Two-factor authentication (2FA) is pretty commonplace these days and offers a second layer of security for apps and games. So if you don't have it set up yet, now's the time! Fortnite two-factor authentication serves a number of purposes, like keeping your account safe, netting you free games, and it's a requirement if you want to send gifts in-game or try your hand in competitive events.
