Activision has announced that PC players of Call of Duty: Black Ops 7 will need to enable Windows Secure Boot and use a system with Trusted Platform Module 2.0 (TPM 2.0) technology. This initiative will begin testing during Season 5 of Call of Duty: Black Ops 6 and Call of Duty: Warzone, but enforcement will not be immediate. The Ricochet anti-cheat team will notify players who have not updated their systems to comply. Activision assures that the TPM 2.0 and Secure Boot processes will not access personal files and will not affect in-game performance. Two-factor authentication (2FA) is encouraged but not yet mandatory, and players using a free trial of Game Pass on PC will be restricted from accessing multiplayer ranked play. Electronic Arts' Battlefield 6 will also incorporate Secure Boot as part of its anti-cheat system, limiting players to Windows.
