How Do HWID Bans Work in Popular Games? (Warzone, Valorant, Fortnite & More)

Modern games don’t just ban accounts — they can ban your entire device. This is known as an HWID ban (Hardware ID ban), and it’s one of the most effective ways anti-cheat systems prevent repeated access.

If you're new to this topic, check out our guide on what HWID (Hardware ID) is .

Overview of how HWID bans work across popular games using modern anti-cheat systems.

---

TL;DR (Too Long; Didn’t Read)

• HWID bans block your device, not just your account
• Games use multiple hardware identifiers
• Modern systems use TPM, Secure Boot, and cloud verification
• Detection varies by game and anti-cheat system

---

How HWID Bans Work (Simple Explanation)

Games generate a hardware fingerprint using components like:

• CPU information
• Motherboard serial
• Storage identifiers
• Network adapter (MAC address)

When flagged, this fingerprint can be used to block access across multiple accounts.

Call of Duty: Warzone (RICOCHET Anti-Cheat – 2026)

• TPM 2.0 (Trusted Platform Module)
• Secure Boot verification
• Cloud-based attestation (Azure)

This system can:

• Verify system integrity before matches
• Block access before gameplay starts
• Combine HWID with system-level trust checks

👉 HWID is now part of a trusted system profile, not just a single identifier.

What this means for players: In Warzone, especially in ranked play, your system must meet strict integrity checks before you can even enter a match. This means players need a properly configured system with TPM and Secure Boot enabled. If your device fails these checks or is flagged, you may be blocked instantly, even on new accounts.

Call of Duty Warzone uses RICOCHET anti-cheat with TPM, Secure Boot, and system integrity checks to detect and block devices.

Valorant (Riot Vanguard)

• Kernel-level anti-cheat
• Runs at system startup
• Tracks multiple hardware identifiers

This makes Valorant one of the strictest environments for HWID bans.

What this means for players: Valorant’s system runs at a deep level of your PC, meaning it can detect issues very early. Players need a clean and stable system, as bans can quickly apply across accounts. Once flagged, returning on the same device becomes extremely difficult due to how aggressively Vanguard tracks hardware and system behaviour.

Valorant’s Vanguard anti-cheat operates at kernel level, using hardware tracking and deep system monitoring to enforce HWID bans.

Fortnite (EAC + Epic Systems)

• Combines account + hardware tracking
• Uses behavioural detection
• Results can vary depending on the system

What this means for players: Fortnite uses a mix of hardware and behavioural detection, so results can be less predictable. Some players may experience temporary restrictions, while others may see repeated flags on new accounts. This means maintaining a consistent and clean system environment is important to avoid issues.

Fortnite combines Easy Anti-Cheat (EAC) with behavioural detection and account tracking to identify and restrict devices.

ARC Raiders (2026)

• Aggressive modern anti-cheat
• Frequent detection updates
• Hardware bans can persist across sessions

What this means for players: ARC Raiders uses newer and more aggressive detection systems, meaning bans can apply quickly and persist across sessions. Players may find that new accounts are flagged almost immediately, making it one of the stricter environments when it comes to device-level tracking.

ARC Raiders uses modern anti-cheat systems with hardware fingerprinting and real-time detection to enforce persistent HWID bans.

---

Rainbow Six Siege (BattlEye)

• Behavioural + hardware detection
• Delayed ban system
• Escalates with repeated detections

What this means for players: Rainbow Six Siege often uses delayed bans, meaning players may not notice an issue immediately. However, repeated detections can lead to stronger restrictions over time. This makes it important for players to maintain consistent system behaviour, as flags can accumulate.

Rainbow Six Siege uses BattlEye anti-cheat with behavioural monitoring and delayed enforcement to detect and escalate bans.

---

Roblox (Evolving Systems)

• Primarily account-based moderation
• Limited hardware tracking
• Systems improving over time

What this means for players: Roblox focuses more on account-level moderation, but hardware tracking is becoming more relevant over time. Players may not always see immediate device bans, but repeated violations can still lead to stronger restrictions as detection systems evolve.

Roblox focuses on account moderation with evolving hardware tracking and device-level restrictions across its platform.

How Modern Anti-Cheat Systems Detect Hardware (Deep Dive)

1. Hardware Fingerprinting

Combines multiple hardware identifiers into a unique device profile.

2. Kernel-Level Anti-Cheat

Allows deep system monitoring and detection of low-level manipulation.

3. TPM & Secure Boot

Ensures system integrity and prevents low-level tampering.

4. Cloud-Based Attestation

Validates system trust remotely before allowing gameplay.

Conclusion

HWID bans are now a core part of modern anti-cheat systems. Games like Warzone, Valorant, and Fortnite use advanced tracking methods that go far beyond simple identifiers.

Understanding these systems helps explain why device-level bans are so effective in preventing repeated access.
