With Season 04 now live, we’re building on our anti-cheat systems to better protect players and ensure fair matches across all platforms. The following security measures are now enabled and actively enforced in-game.
Players who fail Microsoft Azure Attestation (MAA) checks will be placed into a separate matchmaking pool. To access all playlists, players must successfully complete the MAA process. Because the pool of players who haven’t passed our attestation checks is small, access is limited to a select set of playlists to help maintain healthy matchmaking.
Players who do not complete attestation will be limited to Nuketown 24/7 in Call of Duty: Black Ops 7 and Battle Royale Casual in Call of Duty: Warzone. This requirement helps protect the integrity of the game and the experience of the broader community.
How it works:
If your PC isn’t compliant, you will receive a notification that your system failed attestation, and matchmaking access will be adjusted accordingly.
If you attempt to play with party members whose PCs aren’t compliant, you will also receive a message that you’ve failed attestation because at least one party member did not meet secure attestation requirements.
To be fully compliant, your system will need:
For AMD users, versions of AMD’s TPM software in the 3.x.0.x range can return an error during the attestation process, and the fix is to update the system BIOS or firmware.
If you don’t have these features enabled, you will be placed into a separate matchmaking pool. You also won’t be able to match with players whose systems meet our security requirements or with console players.
