Call of Duty: Modern Warfare II will use the same controversial phone requirement system as Overwatch 2
Overwatch 2 found itself in the midst of controversy--not just because of the multiple DDoS attacks it suffered on launch--when it decided to force players to use a phone number to verify their account. The game uses a 2-factor authentication system called SMS Protect, which in theory is designed to prevent disruptive behavior, but in doing so also limits what types of phone numbers are accepted: prepaid phone plans and VOIP numbers are blocked. This led to a lot of outcry from fans, to the point that Blizzard had to partially walk back some of the restrictions, though it still requires having an aged Battle.net account.
Now, with all the ensuing drama regarding the SMS Protect restrictions, Activision Blizzard is going right ahead and implementing it yet again, in the upcoming Call of Duty: Modern Warfare II. A new FAQ page for Battle.net details that in order to access Modern Warfare II at all, you'll need a phone number, and once more, VOIP services and WhatsApp will not work, while prepaid phone numbers "may not work".
