Block chain-Driven Web Authentication with Dynamic Code Generation

Abstract

As we depend more and more on online platforms, keeping user login secure is a top priority. Traditional methods, which often store usernames and passwords on central servers, are increasingly at risk from cyberattacks like data breaches, phishing scams, and identity theft. To overcome these problems, this project suggests a decentralized login system based on block chain technology. Blockchain provides a secure and transparent record where login information are managed safely without a central authority. Smart contracts enable automated checks that are resistant to tampering and unauthorized access. Unlike standard systems, this approach eliminates the single point of failure by spreading data across a blockchain network, ensuring better uptime and security. Users have more control over their online identities because blockchain-based systems avoid storing cleartext passwords or sensitive information in one location. Integrating blockchain with crypto wallets, like MetaMask, further strengthens user login by enabling secure, key-based identity checks. This method not only boosts user confidence and privacy but also fits with the future of the decentralized web (Web3). This proposed solution shows how blockchain can transform login systems by providing a secure, scalable, and transparent alternative to traditional login processes.
