Introduction
In a world where password breaches are making headlines almost daily, managing your digital credentials securely has never been more important. Most people rely on cloud-based password managers — convenient, yes, but they come with a critical vulnerability: if the cloud gets hacked, so do you.
Enter MiixKey — a compact hardware security key with a built-in 2-inch touchscreen that stores and manages your passwords, passkeys, and smart card credentials entirely offline. No cloud. No phone app. No browser extension. Just you and your data, in the palm of your hand.
The project is currently live on Kickstarter, and it has already surpassed its funding goal. Here is everything you need to know.
What Is MiixKey?
MiixKey is a hardware security key and password manager developed by MiixPro. Unlike traditional security keys such as YubiKey or Google Titan — which are excellent for FIDO2 login but offer no display or on-device credential management — MiixKey adds a 2-inch touchscreen that lets you create, search, edit, and manage credentials directly on the device.
It is built around the ESP32-P4, a powerful dual-core 32-bit RISC-V chip running at up to 400 MHz with AI instruction extensions and a floating point unit — serious hardware for a device this small.
Key Features
🔐 Massive Password Storage — Offline
MiixKey can store over 3,000 passwords using KeePass-compatible KDBX files. You can import your existing KeePass or KeePassXC database directly onto the device, or create new credentials on-screen. None of this data ever touches the internet.
🖥️ Built-in 2-Inch Touchscreen
This is the standout feature. Instead of needing a phone or computer to manage your credentials, you do it all on the device itself. Browse, search, add, and delete passwords directly — no companion app required.
🔑 5 Independent Security Key Slots
MiixKey comes with five separate smart card slots, each with its own PIN. Every slot independently supports:
- FIDO2 — for passwordless login
- PIV — for smart card authentication
- OpenPGP — for email encryption and file signing
Each slot can hold up to 64 FIDO2 passkeys, giving you a total of 320 passkeys across the device.
📲 Auto-Fill via USB and Bluetooth
Once set up, MiixKey acts as an HID device (essentially emulating a keyboard) over USB or Bluetooth to automatically fill in your usernames and passwords on connected devices. Works across Windows, macOS, Android, and iOS.
🔒 AES-256 Encryption
All stored data is protected with AES-256 bit encryption — the same standard used by governments and financial institutions worldwide.
📟 Built-in TOTP Generator (2FA)
No need for a separate authenticator app. MiixKey has a built-in TOTP generator for two-factor authentication, and all operations are performed locally without any cloud or online dependency.
💳 NFC Card Storage
MiixKey can store up to 8 NFC cards, useful for building access, transit cards, or contactless payment emulation.
🛠️ Custom Scripts and BADUSB
For power users and developers, MiixKey supports custom scripts and BADUSB functionality, allowing it to emulate a keyboard and automate keystrokes or complex command sequences.
📤 QR Code and NFC Tag Sharing
You can generate QR codes and NFC tags directly on MiixKey to share passwords securely with trusted devices — a neat feature for teams or households.

Who Is It For?
MiixKey is an excellent fit for:
- Privacy-conscious individuals who do not want their passwords stored in the cloud
- Cybersecurity professionals who need multi-slot smart card support
- Developers and power users who want BADUSB/custom script capabilities
- Enterprises and government staff requiring PIV and OpenPGP compliance

If you already use KeePass or KeePassXC and have been looking for a way to carry your database without relying on a phone, MiixKey is a compelling solution.
