No account and no internet connection required\n- Finds your PC automatically, so there is nothing to configure\n- Pair by scanning a QR code, or by entering a pairing code by hand\n- Pair multiple phones, and different phones for different user accounts\n- Wake your PC with Wake-on-LAN before unlocking it\n- Windows and Linux on x64 and ARM, plus macOS\\* on Apple Silicon\n\n### Where it works\n\n**Windows**\n- Login and lock screen\n- UAC prompts\n\n**Linux**\n- Login and lock screen (GDM, SDDM, LightDM, KDE, Cinnamon, Hyprlock)\n- `sudo` and `polkit`\n\n**macOS**\\*\n- `sudo` and system permission prompts\n\n\\* experimental\n\n## Installation\n\nDownload the latest release for your system from the [releases page](https:\u002F\u002Fgithub.com\u002FMeisApps\u002Fpcbu-desktop\u002Freleases), then follow the [installation guide](https:\u002F\u002Fmeis-apps.com\u002Fpc-bio-unlock\u002Fhow-to-install), which walks through the system requirements, the setup and the pairing.\n\n## How it works\n\nWhen your PC needs your password, it asks your paired phone over your local network or Bluetooth. You confirm with your fingerprint or face, and the phone sends back the key that lets your PC unlock itself. Everything the two devices exchange is encrypted so that only they can read it.\n\nWhile pairing you choose how the two devices talk to each other.\n\n**Automatic** means your phone pops up the unlock prompt by itself as soon as your PC asks for it. You can pick the connection it uses:\n\n- **UDP** *(recommended)*: works on any local network, and keeps working when your phone's IP address changes.\n- **TCP**: a little faster, but best with a static IP for your phone.\n- **Bluetooth**: no network needed, ideal for notebooks and tablets on the go, at the cost of some battery life.\n\n**Manual** means nothing waits in the background on your phone. You simply open the app and start the unlock from there, if you prefer it that way.\n\nIf anything ever goes wrong, nothing is lost: hold \u003Ckbd>Left Ctrl\u003C\u002Fkbd> + \u003Ckbd>Left Alt\u003C\u002Fkbd> to cancel, and log in with your password as usual.\n\n## Security & privacy\n\nPC Bio Unlock is designed so that using it does not make your PC easier to break into.\n\n**Your password never leaves your PC.** It is stored encrypted, and the key to it lives only on your paired phone. Your phone never sees your password, it only holds the key, and the password is never sent over the network or to anyone else. Without your phone the stored copy is unreadable, so someone who takes the file off your PC gets nothing usable. On top of that, the file is locked down so that only the system can access it.\n\n**Nothing is bypassed.** The unlock ends with your normal password being checked by Windows or PAM, exactly as if you had typed it. No security policy, account restriction or lockout is skipped.\n\n**Everything is end-to-end encrypted.** Pairing and unlocking are protected with modern authenticated encryption (AES-256-GCM), with keys that are exchanged out of band through the QR code you scan. Every message is signed against tampering and carries a timestamp, so recorded traffic cannot be replayed later to unlock your PC. Each unlock also has to answer a one-time challenge, so an old response is worthless.\n\n**Nothing leaves your network.** There is no account and no telemetry. Whatever your PC and your phone say to each other is encrypted with keys that only those two devices hold, so it is unreadable to anyone else, including us. The only requests that leave your network are the check for a new version and, if you decide to install one, the download itself.\n\n**Your PC stays closed.** The app only accepts connections while you are pairing or while an unlock is actually running, and stops listening again as soon as it is done.\n\n**It's auditable.** The full source of both the app and the login components is in this repository, under the GPL.\n\nFound a security issue? Please report it privately through [GitHub security advisories](https:\u002F\u002Fgithub.com\u002FMeisApps\u002Fpcbu-desktop\u002Fsecurity\u002Fadvisories) instead of a public issue.\n\n## Building from source\n\nYou need CMake 3.22+, a C++23 compiler, Qt 6 and OpenSSL 3. Boost, spdlog, nlohmann\u002Fjson and cpp-httplib are downloaded automatically during configuration.\n\n**Windows**: Visual Studio 2026, the Windows SDK, [Inno Setup](https:\u002F\u002Fjrsoftware.org\u002Fisinfo.php) for the installer, and [vcpkg](https:\u002F\u002Fgithub.com\u002Fmicrosoft\u002Fvcpkg) with `VCPKG_ROOT` set:\n\n```bash\nvcpkg install --overlay-triplets=cmake\u002Fvcpkg-triplets --triplet x64-windows-static openssl\nvcpkg install --overlay-triplets=cmake\u002Fvcpkg-triplets --triplet x64-windows-static-md openssl\n```\n\nFor ARM builds, use the `arm64-windows-static` and `arm64-windows-static-md` triplets instead.\n\n**Linux**\n\n```bash\nsudo apt install build-essential pkg-config cmake git \\\n     libssl-dev libpam-dev libcrypt-dev libbluetooth-dev \\\n     libgl1-mesa-dev libegl1-mesa-dev libxkbcommon-x11-dev libxcb-cursor-dev\n```\n\n**macOS**: Xcode command line tools and Qt for macOS.\n\n### Build\n\n```bash\ncmake -B build -DCMAKE_BUILD_TYPE=Debug\ncmake --build build\n```\n\nQt is detected automatically; pass `-DQT_BASE_DIR=\u003Cpath>` to pick a specific installation.\n\n### Packaging\n\n`pkg\u002Fbuild-desktop.sh` builds and packages a release: a setup executable on Windows, an AppImage on Linux, or a disk image on macOS. Platform, architecture and Qt path are detected automatically, or can be set through the `PLATFORM`, `ARCH` and `QT_BASE_DIR` environment variables.\n\n## Troubleshooting\n\nConnection problems, pairing issues and how to get back into a PC that won't let you in are covered in the [troubleshooting guide](https:\u002F\u002Fmeis-apps.com\u002Fpc-bio-unlock\u002Ftroubleshooting).\n\nFor anything else, the app has two tools built in: a log viewer for both the app and the login component, with a *debug logging* switch in the settings, and an unlock test that lets you try a paired device without locking your screen.\n\n## Contributing\n\nIssues and pull requests are welcome. A few pointers:\n\n- The code style is enforced by the checked-in `.clang-format` and `.clang-tidy`. Please run clang-format before submitting.\n- **Translations**: copy `common\u002Fres\u002Fen_US.json`, translate the values, then register the new file in `common\u002FCMakeLists.txt` (`embed_json`), `common\u002Fsrc\u002Futils\u002FI18n.cpp` and `LocaleHelper`.\n- **Bug reports**: please use the issue template and attach the desktop and module logs; they are what make network and PAM problems diagnosable.\n\n## License\n\n[GNU General Public License v3.0](LICENSE)\n\n## Links\n\n- Website: [meis-apps.com](https:\u002F\u002Fmeis-apps.com)\n- Android app: [Google Play](https:\u002F\u002Fplay.google.com\u002Fstore\u002Fapps\u002Fdetails?id=com.meisapps.pcbiounlock)\n- Support the project: [Ko-fi](https:\u002F\u002Fko-fi.com\u002Fmeisapps)\n","PC Bio Unlock Desktop 是一款用于 Windows 和 Linux 系统的本地身份认证代理工具，实现通过已配对的 Android 手机（利用指纹或人脸识别）安全解锁 PC。其核心功能包括：支持 Wi-Fi\u002FLAN\u002F蓝牙多种本地通信方式、零配置自动设备发现、QR 码或手动码配对、多手机多账户支持、Wake-on-LAN 唤醒联动，以及对登录屏、锁屏、UAC\u002Fpolkit 权限提示等关键场景的深度集成。所有通信端到端加密，密码始终保留在本地，手机仅持有解密密钥。适用于追求便捷与隐私平衡的家庭用户、开发者及企业办公环境（非互联网依赖型场景）。macOS 支持尚处实验阶段。",2,"2026-08-17 02:30:05","trending"]
