About HWID Checker

Hardware IDs appear in software licensing, device security, IT inventory and support workflows, but the term often describes several different things. HWID Checker exists to make those identifiers easier to find, validate and understand without hiding their limitations.

What the site provides

Windows utility — a portable command-line tool that reads identifiers exposed by Windows and device firmware, then creates a composite SHA-256 HWID.
Cross-platform commands — documented Windows, macOS and Linux commands for retrieving individual machine, firmware, disk and network identifiers.
Online checker — local browser tools for generating a browser fingerprint, validating or parsing an identifier, and comparing it with a list.
Ban diagnostic — an educational questionnaire that compares a game restriction with common account, IP and hardware-ban patterns. It cannot query a publisher's private records.
Technical guides — practical explanations of identifier formats, stability, privacy and device-bound licensing.

Our principles

Be precise. A browser fingerprint is not a motherboard UUID, and a format validator cannot prove which device produced an identifier.
Process locally when possible. The browser tools and Windows utility do their core work on the device. The optional validation API receives values submitted to it.
Explain limitations. Hardware identifiers can be missing, generic, duplicated, changed or spoofed; no single value is perfect proof of device identity.
Avoid bypass tooling. The site explains HWID bans and licensing systems but does not provide spoofing or access-control evasion tools.

Technology

The website uses Next.js, TypeScript, Tailwind CSS and next-intl. Browser fingerprints use the Web Crypto API when available. The portable Windows utility is built in Go, and the optional desktop GUI source uses Tauri and Rust.
