In the future, we can improve this code by integrating it with a user authentication system. This will allow users to securely log in to their accounts using OTPs, making it more difficult for hackers to gain unauthorized access. Additionally, we can add a feature that allows users to choose their preferred method of receiving OTPs, such as through SMS or a mobile app. This will provide users with more flexibility and convenience. Furthermore, we can implement machine learning algorithms to detect and prevent fraudulent activities, such as multiple failed OTP attempts or suspicious login locations. This will enhance the security of the system and protect user data. Overall, these improvements will make the code more robust, secure, and user-friendly, providing a better user experience and ensuring the safety of sensitive information.
