I built my own hardware password manager years ago and it works great for me. It is based on a small microprocessor (PIC) that emulates a keyboard via USB and has a small LCD display and 3 buttons. You simply scroll through the menu that lists the name of the thing you are logging into, it does not display the password, you press the button and it enters the password via keyboard USB HID. Works on any OS any device that uses USB keyboard which is basically everything.
Pretty simple, tough to hack, no way to get into it except me (no remote access to it, you have to know how to program it). Bad thing is if I ever lose it I am screwed and would have to change every password, because I don't have any authorization on it, whoever possesses it can plug it in and hit a button and it will dutifully output the passwords. I originally made it because for work I probably type in the same password 50 times a day, with this I just plug it in scroll to the work password and then its just 1 button push each time. Someday I may think of a way of securing it somehow, but for now I just have to make sure I don't lose it!
- mattowen_uk 5y agoI have a teensy sitting in a box somewhere waiting for me to build exactly something like this! Care to share your build process? Regarding initial security - have you though about a button sequence with the 3 buttons after it's plugged in, which 'unlocks' the password list?
- zw123456 5y agohehe ya, i should put it up on my github, you are getting me interested again. For authentication ya, button sequence, or another thing i was thinking might be cool would be NFC. I have a little NFC chip, could make a new version. That would be cool then you could activate it with your phone using an NFC app.
