Abstract :
With the rapid growth of digital platforms and online services, ensuring secure authentication has become a critical requirement for protecting sensitive user information. Many web applications rely on password-based authentication systems, but weak passwords and poor security practices often lead to data breaches and unauthorized access. This research proposes a Secure Login System with Password Strength Analyzer designed to improve authentication security by enforcing strong password policies and secure credential storage mechanisms. The proposed system evaluates password strength in real time based on complexity factors such as length, character diversity, and entropy measurement. Additionally, cryptographic hashing techniques such as bcrypt are used to securely store passwords, preventing plaintext exposure in case of database compromise. The system architecture follows a client-server model where user credentials are validated through secure authentication processes. Experimental evaluation demonstrates that the proposed framework significantly improves resistance against brute-force attacks and weak password vulnerabilities compared to traditional login systems. The system also promotes cybersecurity awareness among users by providing real-time password strength feedback and encouraging secure password practices.
