In today’s digital world, secure user authentication is important for protecting sensitive information and preventing unauthorized access. This paper presents a Secure Email-Based One-Time Password (OTP) Generation and Verification System developed using Flask. The system generates unique and time-limited OTPs and sends them to users through email for secure authentication. Flask is used as the backend framework to efficiently manage OTP generation, email delivery, and verification processes. The system also includes security features such as encryption, secure communication methods, and OTP expiration time to prevent replay attacks and unauthorized access. The proposed system is simple, reliable, and user-friendly, making it suitable for applications such as banking, e-commerce, and web-based services. The results show that the system improves authentication security while maintaining good performance and ease of use.
KEYWORDS
The proposed Email-Based OTP Generation and Verification System provides a secure, efficient, and user-friendly authentication mechanism that enhances access control in modern applications. Developed using Flask, the system ensures smooth integration with backend services while maintaining strong security protocols. By employing unique, time-bound OTPs and encrypted transmission, it effectively reduces risks such as interception, unauthorized access, and brute-force attacks. This system offers a reliable authentication framework, and with further enhancements, it has the potential to become an industry-standard security solution, ensuring safe and seamless digital interactions across various platforms.
