OnlyKey

OnlyKey is a hardware password manager that stores your login credentials offline in a secure USB device. Instead of remembering dozens of passwords, you only need to remember one PIN code to access all your accounts. The device types your credentials directly into your computer when you press its buttons, keeping your passwords isolated from potentially compromised systems.

What sets OnlyKey apart is its complete lack of dependency on software or cloud services. All data is encrypted and stored locally on the device, making it immune to remote attacks and data breaches. It supports up to 24 accounts with passwords and 24 two-factor authentication codes, and features a backup slot that lets you recover your data if you lose your primary device. The open-source firmware allows security experts to verify its integrity and customize its functionality.

This tool is ideal for security professionals, IT administrators, and anyone who values privacy and wants to avoid cloud-based password managers. It's particularly useful for protecting sensitive work accounts, securing cryptocurrency wallets, and maintaining login security while traveling without relying on internet connectivity.
