Integrating passphrases as an authentication mechanism in E-commerce

E-commerce has brought drastic changes in the way business transactions are conducted prompting banks and other businesses to adopt electronic payment systems. It not only offers the banking industry and other businesses a great opportunity, but also creates risks and vulnerabilities. The main objective of this research was to address security issues related with password-based authentication mechanism in e-commerce websites such as password cracking. The research intended to design a system that had the capabilities to mitigate password guessing and brute force attack since passphrases allow special characters like space. It is recommended that passphrases should be designed to be user-selected since they have better usability than system generated passwords. Users should also exercise extreme caution when writing down or storing passphrases.
