User authentication is one of the most important security characteristics of any system given today's globalized digital life style. The safety and security of sensitive data, privacy and also critical infrastructure relies primarily on authentication. Amongst all authentication schemes, text-based passwords are the most deployed across various platforms, thus the importance of evaluating user password management practice cannot be overemphasized. This research, via, a case study aimed at establishing the theoretical password knowledge in comparison to actual password management practice of staff and students from Information Technology (IT) inclined departments of the Federal University of Technology, Minna. Results from the survey reveal that the target respondents are knowledgeable on good password management policies. However, actual password practice results by the respondents showed that they do not comply and effectively implement the theoretical password knowledge they possess. Thus it can be concluded that there is a significant difference between what respondents know compared to their actual practice. Numerous implications abound when this is the case as it makes users more vulnerable to security risks of unauthorized access by unauthorized users.
