Ah, passwords. Regardless of what system you use, they’re a pain in the arse to manage, remember or access. But maybe there’s a solution. What about making a USB dongle that enters and creates new passwords every time you plug it in?
Joonas Pihlajamaa decided to give it a try, and put together this little USB drive. Every time he plugs it into a PC, it enters his password. Tap Caps Lock four times in succession, and it generates a new password ready for next time.
To make it, he gutted a USB stick and created some new circuitry using an Attiny chip, a handful of resistors, a couple of diodes and a scrap of breadboard. It looks easy enough that I could do it — which says quite a lot.
If you fancy having a go, he’s gives a full rundown of the process in this guide. [Code and Life via Hack a Day]

Does it use the same password for all sites? If not, how does it know which password to use? Also, how would it deal with passwords that have different requirements (e.g. length, character types used) etc.
