I am building a password manager on my Raspberry Pi Zero, using `pass` – the UNIX Password Manager as a platform. (See: passwordstore.org)
This Project was inspired by the Hackaday articles about using the RPi Zero as a USB Gadget from [LadyAda] and [gbaman], and the RPi-Wifi hack from [ajlitt].
Using a ‘Composite USB Gadget’ and the libcomposite driver, the Pi will present itself as a HID (Keyboard) and Ethernet adapter (SSH). Using the on-device OLED screen and the button matrix, you can select a desired password and username combination to send to the connected computer and enter the master passphrase.
Since `pass` can update the password store over `git`, I decided to give the ESP-hack a try, so you can fetch your latest passwords on the fly.
The Ethernet adapter will be useful for debugging, but also to change passwords on the device or perhaps serving a web panel to select and display passwords.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
