Abstract

This paper presents a secure web authentication system that balances stringent security measures with a responsive user experience. The proposed system is built using Java Servlet, MySQL, and the Bcrypt encryption algorithm to protect user credentials while maintaining smooth interaction during login and registration processes. Although Bcrypt’s salted hashing and iterative design effectively defend against brute-force and rainbow table attacks, its computational intensity can introduce noticeable delays during password verification. To mitigate this issue, the system integrates real-time user feedback and context-sensitive error messages—designed under anti-rude principles—to maintain user trust and tolerance during authentication delays. The registration process ensures that user-provided information such as usernames, emails, and passwords are validated on the front end with JavaScript, while the backend further verifies inputs to prevent SQL injection and malicious entries. The login module uses session management to securely maintain user state and implements a lockout mechanism after repeated failed attempts to further enhance security. Experimental evaluations indicate that the system’s modular design and interactive feedback mechanisms significantly improve the overall user experience despite inherent delays introduced by secure password hashing.
