Fortnite will require Secure Boot, TPM and IOMMU on PC

Starting Thursday, Feb. 19, Fortnite will add new anti-cheat requirements for Windows PC players. The game will require Secure Boot, TPM and IOMMU, joining Call of Duty: Black Ops 7, Battlefield 6, Valorant, Highguard and League of Legends in enforcing those checks.

Secure Boot is a hardware-level BIOS feature that prevents malicious software from infiltrating the system and helps block kernel-level cheats. TPM — specifically TPM 2.0 — is a Trusted Platform Module and another hardware-level protection. IOMMU stands for I/O Memory Management Unit.

Both TPM and Secure Boot are usually enabled by default on new Windows 11 PCs, but older machines will need to update to the latest operating system. If either setting is disabled, players must enable them in their BIOS; using a tutorial is recommended, since changing BIOS settings without clear guidance can be risky.
