In order to protect players’ accounts and prevent cheating, Activision Blizzard has announced that MW2 will feature Overwatch 2’s controversial phone number requirement.

Call of Duty Modern Warfare 2 seems like it’s set to follow the same controversial path as Overwatch 2 by including the SMS Protect two-factor authentication.

While many players felt it was an unnecessary feature in Overwatch 2, Activision Blizzard is doubling down on its methods.

This isn’t the first controversy to hit Modern Warfare 2. Recently fans began campaigning for the return of an iconic Call of Duty feature.

Players will need to register a mobile phone number under a contract plan in order to play Call of Duty Modern Warfare 2 on PC.

This is according to an updated post on Blizzard’s website, spotted by PC Gamer. It details mobile phone requirements to access their launcher,

The post reads: “Call of Duty: Modern Warfare II, newly created Overwatch 2 accounts, and newly created Call of Duty: Modern Warfare accounts require a phone number.”

Essentially, players will need to connect their mobile phone number to their account in order to access MW2. This will supposedly reduce cheating and offer players a way of recovering their account.

It is worth noting that players with prepaid plans or pay-as-you-go contracts will not be able to register a number and, therefore, will be unable to access MW2.

Additionally, this won’t just affect users on If you’re not sure whether you should play MW2 on or Steam, then keep in mind you will also have to register a number on Steam.

However, Blizzard removed the same mobile phone number requirement for some people on Overwatch 2 just days after it launched. It remains to be seen how long this requirement will last for MW2.

After all, it is unlikely that Activision Blizzard will want to alienate its player base after the monolithic success of Modern Warfare 2’s Beta.
