Call of Duty: "Failed Attestation Status"

Failed Attestation Status

Your PC did not pass Call of Duty's security check (TPM 2.0 and Secure Boot). In Black Ops 7 and Warzone you lose access to some modes such as Ranked Play and may be matched with other non-compliant players; Modern Warfare 4 blocks all online modes.

Is Call of Duty down right now? Operational: 11 problem reports in the last hour. If it were down for everyone, this error could come from there; right now it looks normal.

Fix it

How to fix "Failed Attestation Status"

Run the Call of Duty Secure Attestation Wizard to see which setting fails.
Open tpm.msc and check your TPM Manufacturer Version; AMD 3.x.0.x and Intel INTC 302.12 or 303.12 versions may need a BIOS update.
Ask your motherboard or PC maker for a BIOS firmware update (Lenovo users should open a ticket with Lenovo).
If you still fail after all steps, send Activision a TPM incompatibility report.
