QuantumAuth Client\n![Powered by QuantumAuth](https://img.shields.io/badge/Powered%20By-QuantumAuth-1a1a1a?style=for-the-badge\u0026logo=dependabot)\n\n[![Release](https://img.shields.io/github/v/release/quantumauth-io/quantum-auth-client)](https://github.com/quantumauth-io/quantum-auth-client/releases)\n![License](https://img.shields.io/badge/License-Apache%202.0-blue.svg)\n![Go Version](https://img.shields.io/badge/Go-1.25+-00ADD8?logo=go)\n![Platforms](https://img.shields.io/badge/Platforms-Linux%20%7C%20macOS%20%7C%20Windows-lightgrey)\n![Status](https://img.shields.io/badge/Status-Active-brightgreen)\n\nThe **QuantumAuth Client** is a lightweight, open-source system agent that provides **device-bound authentication** using secure hardware such as **TPM** (with Secure Enclave support coming soon).  \nIt runs locally on the user’s device and manages a unique cryptographic identity used to sign requests and authenticate with QuantumAuth-enabled applications.\n\nThe client handles:\n\n- Device registration\n- Hardware-backed key generation\n- Local signing of authentication requests\n- Secure communication with the QuantumAuth backend\n\n\n\n### TPM / Secure Hardware Support\n\n- Linux + Windows use TPM 2.0 for hardware-backed keys\n- macOS Secure Enclave support is in development\n- If no secure hardware is available, the client automatically falls back to software keys\n\n## 📦 Installation\n\n### Linux\n\n\n[![Get it from the Snap Store](https://snapcraft.io/en/dark/install.svg)](https://snapcraft.io/quantum-auth-client)\n\nManual installation\n\n1. **Download** the latest
