Password manager
Introduction
A password manager (similar to a physical crypto wallet), that can be interacted with using a remote. The user can save multiple passwords by using the menus of the wallet. On the LCD are displayed the saved passwords and the status. Passwords can be added, deleted and saved to the EEPROM. It is intended to be used with highly sensitive passwords such as banking passwords (card pins, etc) that should never touch the internet.
General description
Hardware Design
Parts list: Arduino UNO R3, Infrared receiver, remote control, Alphanumeric LCD, breadboard, resistor 1k, jumper wires
Software Design
Firmware:
- developed using: CLion (+PlatformIO) and Arduino IDE (C++)
- the user can register a new password, if he correctly guessed the 'master password'
- the user can wipe all passwords, but not the 'master password'
- the user can lock and unlock the device
- all passwords are saved in EEPROM
- companion cross-platform Mobile app (similar to 2 Factor), used to get the 'master password' from the seed (Dart & Flutter)
Results
The device works as expected, passwords are saved and retrieved from EEPROM, there seem to be no bugs in the software, neither for the Arduino nor for the companion app.
Conclusions
This was the first project of this type that I've made, it helped me better understand the labs, and how hardware works.
