Product idea! A little e-ink display (let's call it a Password Storage Device or PSD) with a tiny processor and enough memory to store all your passwords. Make them cheap enough that you can have a few redundant copies in various places. - OS sees the device as a keyboard - Two versions. One with bluetooth, and one with only USB for a little more security. - Open source software package to sync your collection of PSD…
