Game hardware bans identify a PC through publisher-specific device signals and enforcement systems—not one universal, publicly documented fingerprint. Riot discusses a TPM Endorsement Key as a possible hardware identity signal in Vanguard, while Activision says its system validates hardware without publishing a definitive list of identifiers. A device restriction is different from an account ban, and the exact matching rules vary or remain undisclosed.
What a hardware ban attaches to
An account ban restricts an account. A hardware ban, also called an HWID ban, associates a restriction with a device or its physical components. A publisher may apply one or both types of enforcement.

Riot Games Support describes an HWID ban as banning a computer’s physical components rather than only an account. Riot says the restriction is intended to prevent service access from that device regardless of which account is used. Activision likewise says its Call of Duty hardware bans apply to the device rather than the account. Riot’s explanation of HWID bans and Activision’s enforcement policy describe those publisher-specific approaches.

Which PC hardware identifiers do games use?
There is no supported universal list of motherboard, drive, network, Windows, or other identifiers that every game uses. Publishers disclose different details, and they do not publish enough information to reconstruct a general identification formula.

Riot and Vanguard: a TPM example
Riot’s technical discussion of Vanguard describes the TPM’s Endorsement Key (EK), a key stored in the TPM’s non-volatile memory, as something that could serve as a hardware identity signal. This is a specific example from Riot’s own system; it does not establish that every anti-cheat reads a TPM EK, or disclose every signal Riot uses. Riot’s Vanguard technical article also discusses TPM requirements, driver attestation, and IOMMU security. Those are anti-cheat integrity measures, not necessarily identifiers used to match a ban.
Activision: hardware validation, identifiers undisclosed
Activision says RICOCHET uses client- and server-side detection, monitors relevant applications during gameplay, analyzes gameplay anomalies, and validates that hardware has not been tampered with. Its policy does not name the exact identifiers used to recognize a PC. The description therefore supports the existence of hardware validation, not claims about a particular serial number or a fixed set of fields.

EA: data-handling statements, not a ban formula
EA says EA anticheat runs while a protected game is running and that its processes shut down when the game closes. EA also says it looks only at information needed for anti-cheat purposes and uses hashing to create unique identifiers, discarding original information where possible. These are EA’s published statements about EA anticheat; they do not establish a universal hardware-ban method or show that every such identifier is used to enforce a ban. EA’s explanation of EA anticheat and Battlefield gives its account of runtime and data handling.

| Publisher | What is disclosed | Device or account scope | Review or appeal information |
|---|---|---|---|
| Riot Games / Vanguard | Riot discusses physical-component restrictions and a TPM Endorsement Key as a possible hardware identity signal. | Riot says an HWID restriction applies to the device; another account using the banned computer can also face restrictions. | Riot documents reevaluation for certain cases. Removal is not guaranteed, and verifiable threats are treated differently. |
| Activision / RICOCHET | Activision describes client- and server-side detection, gameplay analysis, and hardware validation, but does not name the identifiers used to recognize a PC. | Hardware bans apply to the device and may affect online gameplay across Call of Duty titles. | Activision says hardware bans are not eligible for appeal; duration may vary. |
| Electronic Arts | EA describes anticheat runtime and data-handling practices, including hashing to create unique identifiers. | EA’s cited article does not specify how these statements map to a device-ban policy. | EA’s cited article does not describe a hardware-ban review route. |
These differences matter: a statement about anticheat data handling or system integrity does not, by itself, prove that a particular value is a ban identifier.

Can a hardware ban affect a shared or used PC?
Yes. Riot warns that logging into a computer with an HWID ban can result in device access restrictions and a time-limited ban on the account used there. Activision warns that a restriction may remain on a secondhand, shared, or public device. If you are considering a used PC, check the relevant publisher’s current policy; the cited policies do not provide a universal tool that certifies a computer as unrestricted.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Will replacing a part or reinstalling the game remove a ban?
The official sources do not establish that changing one component reliably removes a hardware ban. Do not treat online lists of identifiers or claims about swapping a particular part as a dependable fix.

For Riot’s VAN 152 error, Riot says the device has been restricted because of an HWID ban. Reinstalling Vanguard or the game, changing the connection, and restarting the PC will not remove that restriction. Riot also says deleting the account does not remove an HWID ban. Riot’s VAN 152 support page explains the code and its stated non-fixes.
Quick Recap
What to do if you think a restriction is wrong
- Identify the publisher and message. For VAN 152, Riot identifies the problem as a device restriction, not a connection or installation failure.
- Use the publisher’s official support route. Riot documents a support request and reevaluation process for eligible cases, but does not guarantee removal. For Call of Duty, consult Activision’s current security and enforcement policy; Activision says hardware bans cannot be appealed.
- Avoid unofficial “fixes.” The cited publisher sources do not validate commercial spoofing tools or show that they can accurately diagnose or remove a restriction.
