OTP-Verification-System

Project Overview

The OTP Verification System is a Python-based application designed to enhance user authentication by generating and validating One-Time Passwords (OTPs) via email. It ensures secure access to sensitive information or actions with a focus on simplicity, reliability, and security.

Project Structure:

The project consists of two main components: the backend logic and the graphical user interface (GUI). The backend logic handles OTP generation, email sending, and OTP verification, while the GUI provides a user-friendly interface for interacting with the system. Refer below file

• Backend components : OTPverify_Backend.py
• GUI components : OTPverify_GUI.py

Methodologies and Tools

• Tools: Python, PyQt5, Tkinter, Smtplib
• Methodologies: Secure OTP generation, Email communication protocols
