| dc.description.abstract | With the growth of online platforms, the need for authentication across multiple accounts has become a problem, especially for elderly users, who face significant challenges. Cognitive difficulties associated with aging make it harder to memorize multiple passwords, leading to password reuse or the selection of simple combinations, which seriously compromises online security. In this project, we investigated solutions that could ease the authentication process for the elderly. Although methods such as sound-based authentication, drawings, or tokens already exist, they present certain limitations. The need to modify existing systems to integrate these methods, the time-consuming authentication process, and the reliance on additional devices are some examples of these limitations. As regard as user-centered design and iterative prototyping, we developed a password manager involving 9 elderly participants and an expert throughout the development process. We applied algorithms such as Signal and Secret Sharing to ensure the security of user data, enabling the safe storage of credentials in the Cloud and their interpretation by caregivers. The final prototype was evaluated with 17 elderly participants using the System Usability Scale (SUS) questionnaire. We obtained an average score of 81.3, suggesting that our prototype is easy to use by the target audience. | pt_PT |
