Password managers are an easy way to improve your password security. If you’ve ever wanted a physical device that could hold passwords instead, Adafruit has you covered.


To make this, you’ll need a Circuit Playground board, a battery, and some copper foil. This password vault stores 10 passwords, then maps each one to a button. To use it, you’ll plug the vault into a computer, head to a login page, then tap the button to paste in your password, making it so you don’t need to remember a complicated password. This is handy for places where a password manager might not help you, like your computer’s login or even your password manger’s master password. Of course, it’s only as secure as you can keep a physical object, so if you go this route, be sure you don’t lose it. Even if you don’t use it, it’s a fun idea that’s applicable to other projects. Head over to Adafruit for the full guide.
