OTP Based Door Lock System with Mobile Application using Arduino UNO and ESP8266 Wi-Fi module

Today, installing a home security system is a critical study in implementing cutting-edge technology to attain this purpose. One of the most useful technologies to allow remote monitoring of various household appliances is the wireless network technology. This article intends to offer a security system based on Arduino technology, in which the door lock and Wi-Fi are combined to create a fantastic powerful system along with a mobile application to send a secure password, as well as to notify the owner about the time of arrival by providing them with a User ID. As a result, only owners or authorized personnel can be permitted access through the door. The system operates by sending an OTP on user click and opening the attached lock if the entered code is correctly verified. In this study, we look at how to use Wi-Fi connection and OTP built into cellphones to supplement existing door lock system issues. This system uses OTP (One-Time-Password) authentication and an Arduino smartphone-based design to create a wireless OTP door lock system that allows users to live a more convenient and secure life free of the fear of theft and other crimes.
