Unlike traditional YubiKeys that require a phone or computer for setup, MiixKey lets users create, edit, and manage everything directly on the device. It’s designed for power users, crypto holders, developers, and anyone serious about digital security. We all have too many passwords: email, banking, social media, work accounts—the list is endless. Forgetting one is frustrating, storing them in the cloud feels risky, and writing them down is unsafe. What if you could manage everything securely on one offline device with its own screen, requiring no phone or computer for setup? Introducing MiixProKey—a powerful hardware security key with a built-in 2-inch touchscreen, allowing you to set up, edit, search, and delete passwords directly on the device - completely offline. Protect your privacy using an offline secure key that allows one-tap auto-fill and instant data wiping in dangerous situations. Most traditional keys are limited in storage (e.g., one NFC, one FIDO). MiixProKey changes this: NFC: Store up to eight NFC cards and switch between them instantly. Smart Card Slots: Features five smart card slots—essentially five separate YubiKeys in one device. Easily switch between slots, functions, and connection methods (USB, Bluetooth, NFC). Comprehensive Protocols: Each slot supports FIDO2, PIV, and OpenPGP simultaneously, with individual PIN protection. You get up to 320 total FIDO2 credentials across all slots. Password Manager: Stores and manages over 3,000 passwords with full KeePass KDBX support. It utilizes HID mode for auto-fill on any website via USB or Bluetooth. You can manually enter data on the device or use one-click import feature to transfer saved passwords from Chrome or Edge. For enterprise environments, one compact MiixProKey can be securely shared among five employees (e.g., in finance or R&D). Each user holds the PIN for their dedicated smart card slot, keeping their specific credentials private. Security and privacy are paramount. MiixProKey works entirely offline with no cloud sync or internet connection required. Access requires the device and must pass multiple layers of hardware-level protection based on the ESP32-P4 chip: Secure Boot v2: Verifies firmware integrity on every reboot to prevent malware. Flash AES-256 Encryption: Encrypts all stored data at the hardware level. NVS + PIN HMAC Encryption: Protects critical settings and PINs with unique keys. We have included specialized modes for enhanced safety: Create a second, decoy data vault. If under coercion, enter the special Danger Mode. The device will display the fake vault while the real vault is instantly and permanently wiped. Emergency Mode: For critical information requiring delayed access. Set an Emergency PIN and activation delay time (up to 64 hours). A trusted person must enter the PIN and keep the device continuously powered via USB for the entire duration (e.g., 48 hours) to unlock the vault. Designed for long-lasting durability, the MiixProKey shell is made of aluminum alloy with solid brass, gold-plated buttons, and a sturdy keychain loop. Key Use Cases: Find & Auto-Fill: One-tap fill via USB/Bluetooth directly into browsers or apps. Passwordless Login (FIDO2 / Passkeys): Log in to Google, GitHub, Microsoft, and Proton by approving on-screen. Secure Sharing: Long-press to generate a QR code or NFC tag to share credentials safely, leaving no history in chat apps. Access Control: Store up to 8 portable NFC cards for doors, elevators, and offices. TOTP/2FA: Built-in dynamic 6-digit code generator eliminates need for phone apps. Custom Scripts (BADUSB): Write scripts for automated keystrokes and command entry. OpenPGP & PIV: Supports up to 5 independent keys simultaneously to sign emails, encrypt files, authenticate SSH.
