Okay so passwords are actually pretty cool. The problem is that the're are so many of them. I am 100% not the first person to try and tackle the issue of there being so many passwords to everything. There are already both hardware and software solutions to try and fix that. I do not like the software solutions because that presents a singular link, that once broken, can cause a tremendous number of problems. The whole purpose of a password is that it is a unique bit of information that can only unlock one account. A password manager is like making sure your boat doesn't sink by plugging the entire hull with a cork.
Now, my solution doesn't completely solve that problem. If you had access to this device you might be able to get the passwords stored inside it, but since it is completely separate from the internet and your computer/phone/etc, you would have to have hands-on access to it, making it way more difficult to break into (especially considering you could lock it up or something.
Okay so there's like a load of these already up here on Hackaday, but I was mostly inspired by a project I saw quite a while ago ( I cannot seem to find it anymore, if I do I'll post it). So many solutions don't really look like something that I would actually find useful, so I'm working on making something that works for me.
Also now I'm messing with PCB design for this. I am not an electrical engineer (mechanical actually) so I don't really know what I'm doing but hey, we've got bodges.
