Call of Duty: Warzone has implemented a new requirement for free-to-play players that should cut down on the number of cheaters.
Following the example of CS:GO and other free-to-play games, Call of Duty: Warzone now requires two-step SMS verification for its free-to-play players on PC.
This basically means anyone who doesn’t own the full game must tie an active mobile number to their profile, which they’ll be receiving a SMS message on, similar to how two-factor authentication works over email.
