# QuantumAuth Client
[](https://github.com/quantumauth-io/quantum-auth-client/releases)
The **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).
It runs locally on the user’s device and manages a unique cryptographic identity used to sign requests and authenticate with QuantumAuth-enabled applications.
The client handles:
- Device registration
- Hardware-backed key generation
- Local signing of authentication requests
- Secure communication with the QuantumAuth backend
### TPM / Secure Hardware Support
- Linux + Windows use TPM 2.0 for hardware-backed keys
- macOS Secure Enclave support is in development
- If no secure hardware is available, the client automatically falls back to software keys
## 📦 Installation
