Frequently Asked Questions

QuantumShield is the world's first quantum-safe security key that uses post-quantum cryptography (PQC) to protect your data from future quantum computer attacks. It combines NIST-approved ML-KEM encryption with quantum random number generation (QRNG) for maximum security.

Quantum computers pose a significant threat to current encryption methods. "Harvest now, decrypt later" attacks allow adversaries to collect encrypted data today and decrypt it once quantum computers become powerful enough. QuantumShield protects against these future threats.

Traditional security keys use RSA or ECC encryption, which will be vulnerable to quantum attacks. QuantumShield uses NIST-approved post-quantum cryptographic algorithms (ML-KEM and ML-DSA) that are resistant to both classical and quantum computer attacks.

Yes! QuantumShield supports FIDO2/WebAuthn standards, making it compatible with thousands of websites and services including Google, Microsoft, GitHub, Dropbox, and more. It works alongside your existing authentication methods.

QuantumShield uses NIST-approved post-quantum cryptographic algorithms: ML-KEM-768 (QuantumShield One) or ML-KEM-1024 (QuantumShield Pro) for key encapsulation, and ML-DSA for digital signatures. It also includes a hardware quantum random number generator (QRNG).

QuantumShield One uses ML-KEM-768 encryption and is designed for personal use with USB-C and NFC connectivity. QuantumShield Pro uses ML-KEM-1024 (higher security), adds Bluetooth, includes advanced QRNG with entropy export, tamper-evident enclosure, and offers enterprise features like PKCS#11 support.

Yes! QuantumShield performs all cryptographic operations locally on the device. It doesn't require internet connectivity for authentication. However, you'll need internet to register it with online services.

Your QuantumShield is PIN-protected and will lock after multiple failed attempts. We recommend setting up backup authentication methods on your accounts and storing recovery codes in a secure location. Consider purchasing a second key as a backup.

Setting up is easy: 1) Connect your QuantumShield to your device, 2) Download the QuantumShield Manager software, 3) Initialize your key with a PIN, 4) Register it with your accounts. See our Getting Started guide for detailed instructions.

QuantumShield works with Windows 10+, macOS 11.0+, Linux (Ubuntu 20.04+), Chrome OS, Android 8.0+, and iOS 14.0+. It supports all major browsers including Chrome, Firefox, Edge, and Safari.

Yes! You can use your QuantumShield with unlimited devices. Simply connect it to any compatible device and use it for authentication. Your security key is portable and works across all your devices.

Firmware updates are delivered through the QuantumShield Manager software. When an update is available, you'll see a notification. Simply click "Update" and follow the prompts. Your key will never lose data during updates.

QuantumShield stores cryptographic keys and credentials securely in its tamper-resistant chip. No personal information, passwords, or browsing data is stored. All data is encrypted and protected by your PIN.

QuantumShield is designed with multiple security layers: post-quantum encryption, secure element chip, PIN protection, and optional biometric verification. It meets FIPS 140-3 Level 3 and Common Criteria EAL6+ certifications. While no device is 100% unhackable, QuantumShield provides military-grade protection.

QuantumShield is certified with FIPS 140-3 Level 3, Common Criteria EAL6+, NIST PQC approval, SOC 2 Type II compliance, and meets industry standards for hardware security.

No. QuantumShield does not track, log, or transmit your usage data. All operations are performed locally on the device. We respect your privacy and do not collect any personal information.

QuantumShield One includes a 2-year warranty, and QuantumShield Pro includes a 5-year warranty. We cover manufacturing defects and hardware failures. Warranty does not cover physical damage, loss, or theft.

We offer a 30-day money-back guarantee. If you're not satisfied with your QuantumShield, return it within 30 days for a full refund, no questions asked.
