Abstract: Password security is a major concern in today's digital world. This project presents a Hardware Password Manager using the ESP32 microcontroller. The system generates secure random passwords using the ESP32's Hardware Random Number Generator (HRNG), encrypts them using the XTEA algorithm, and stores them in EEPROM memory. The encrypted passwords are transmitted through UART communication and decrypted on a computer using a Python application. The proposed system provides a secure, reliable, and low-cost solution for password management
