ZeroKeyUSB is more than just an offline password manager—it’s a portable, hardware-based vault that lets you securely carry your most sensitive credentials anywhere, without relying on apps, clouds, or internet access. Designed for professionals and teams who need to move fast and stay secure, it stores up to 64 encrypted credentials in secure EEPROM memory, protected by a PIN-based authentication system with signature verification.

With a crisp 128x32 OLED display and an intuitive capacitive touch interface, managing passwords is fast and frustration-free—even on the go. ZeroKeyUSB is powered via USB Type-C, requiring no batteries or charging, and is fully compatible with computers, smartphones, and any device that supports USB HID. Built to be water- and dust-resistant, it’s a durable, ultra-portable solution for anyone who values both security and convenience.

Keep it Secret, Keep it Safe

Online password managers have made it easy to store and sync credentials—but at the cost of entrusting your most sensitive data to cloud services and third-party platforms. Recent high-profile breaches have shown just how vulnerable these solutions can be. Even strong encryption can’t protect your data if the platform itself is compromised.

ZeroKeyUSB takes a different approach: it never connects to the internet, never installs software on your devices, and never leaves a digital trace. Your credentials are stored securely in encrypted hardware memory and only accessible via physical interaction using a PIN-protected, tamper-resistant resin-embedded system.

Whether you’re an individual looking for a private and portable alternative to mainstream password managers, an IT technician working across systems, or a crypto enthusiast who needs a reliable offline vault. It’s simple to use, yet hardened by design, and designed to last.
