Comparing a Store-Less Password Manager With Traditional Password-Only Authentication

This paper presents a comprehensive usability evaluation of HIPPO (Hidden-Password Online Password), a novel store-less password manager, compared to traditional password-only authentication methods. In the digital age, robust password management solutions are essential to mitigate cognitive burdens and enhance security. Unlike conventional store-based password managers, HIPPO dynamically generates passwords without storing them, significantly reducing the risk of data breaches. Our study involved 25 participants who performed tasks such as installation, configuration, password updating, and login using both HIPPO and traditional methods. The findings reveal that HIPPO offers significant security advantages and is perceived as more secure and trustworthy by users. While HIPPO introduces additional steps for password generation and entry, participants reported higher satisfaction and ease of use compared to traditional password-only authentication. This study highlights the trade-offs between security and usability in password management, providing valuable insights for developing more user-friendly and secure password management tools.
