OTP Based Smart Wireless Locking System with Arduino for Home Security

One novel approach to improving the safety and usability of conventional locking systems is the OTPbased smart Wireless Locking System that makes use of Arduino. An easy-to-use, secure lock system based on OneTime Password (OTP) authentication has been developed here by combining the power of wireless communication technologies with the capabilities of the Arduino microcontroller. Users must create a one-time password (OTP) using a specific mobile app in order to access the system. The one-time password (OTP) is safely sent to the command centre over a wireless communication protocol like Bluetooth or GSM. The specified wireless lock module is instructed to unlock by the central control unit after the validity of the one-time password (OTP) has been verified. A number of cutting-edge features have been included into the system to improve its usefulness and security. To start, the one-time password (OTP) increases security by reducing the likelihood of unauthorized access by using different passwords for each authentication attempt. Secure, dependable, and easy to use, the OTP-based smart Wireless Locking System utilising Arduino provides a contemporary answer to access control problems.
