Blockchain-Based Auxiliary Systems for Password Management

Authentication usually involves a combination of a username and password for the identity information process. Historically, users have had to find ways to manage them, typically by memorizing or noting them down separately. Blockchain-based Auxiliary System for Password Management (BAS-PM), which evolved from Distributed Ledger Technology (DLT) Frameworks, is designed to help users store their passwords securely and permanently. Passwords have been a simple yet effective means to protect systems from unauthorized access for years. They are also sensitive personal data that need to be protected by data privacy laws such as the GDPR. For cybersecurity and data privacy purposes, this research aims to propose a Blockchain-based Auxiliary System for Password Management (BAS-PM). The cost-effectiveness and robustness of blockchain technology make it an attractive solution for global password management. This article explores the use of blockchain in password management applications without relying on a centralized server. Experimental results indicate that blockchain-based methods have outperformed traditional methods.
