Minneapolis hacker sigFLUP designed this cool box for managing her passwords.

This automatically stores generated and types all my usernames and passwords. It’s a pretty simple system. It’s a bitsy at89s5131 atmel 8051-ish microcontroller. This is a usb microcontroller and I’ve programmed it to look like a standard usb-keyboard.

<...> it has eeprom to store our passwords. The random number generator is seeded by delays between keypresses so I would imagine it’s fairly hard to predict.

You can download the schematic (.pdf) but sigFLUP didn’t provide the source code. Maybe if we asked nicely? [Via Hack-a-Day]
