While we’re excited about our progress and system updates, combating cheaters will continue to be an ongoing battle. Also, and just in general, don’t fire at your teammates. We are confident that we’ve addressed this for launch.

While we certainly appreciate how much of a team player our security systems are, this issue only persisted for a short period on Sunday before being resolved. One system that did unjustly impact players was a system that kicked (not banned) users out of matches for friendly fire – whether it was accidental or intentional. Additionally, our security and data engineers have confirmed that there was not a bug possible which would have allowed this to happen during the beta. We have investigated this thoroughly and have determined that crashing issues did not cause unjust bans.

There were a small number of players who reported beta crashes that appeared to cause their accounts to be permanently banned.

Call of Duty does not use SMS verification data for marketing purposes. The SMS requirement for game access is used for security purposes only. As the illicit account market adjusted to our security enforcement, #TeamRICOCHET started seeing more cheaters attempt to access Warzone from Modern Warfare to bypass the SMS policy, so the security team recommended the update to further combat the illicit account market. Prior to this change, new accounts in Modern Warfare could access Warzone without a SMS security check. In August 2022, we updated the SMS policy for new players of Call of Duty: Modern Warfare (2019), requiring a text-enabled mobile phone number to play the game. This helps our security team to maintain account and game security in order to provide a safe, fair, and fun gaming experience for all our players. SMS verification is critical to our anti-cheat enforcement efforts, tackling illicit account creation at its source. A mobile phone number must be linked to your Steam Account to play Modern Warfare II on that platform. The SMS policy for Modern Warfare II and Warzone 2.0 on is the same as the requirement for Call of Duty: Warzone on PC, which was implemented in May 2020. Existing Call of Duty®: Warzone™ players that have previously verified their account will not be required to provide any additional information to access Modern Warfare II and Warzone™ 2.0. A text-enabled mobile phone number is required to play Call of Duty: Modern Warfare II on PC.
