Blizzard has partially walked back a controversial policy that required Overwatch 2 players to confirm a valid mobile phone number to play the game. Now, players "with a connected Battle.net account"—a group Blizzard says includes "a majority of existing Overwatch players"— will be able to avoid that requirement.

Blizzard originally announced late last month that all Overwatch 2 players would be required to sign up for its "SMS Protect" service with a valid phone number. The move was sold as a way to bring "meaningful change when it comes to disruptive play" in the game.
