<![CDATA[The increasing number of digital accounts forces users to manage multiplepasswords, yet many still rely on insecure storage methods, such as reusingthe same password across various platforms or manually taking notes. Furthermore,several available password manager applications continue to faceusability and user experience issues, making them less appealing and difficultfor new users to navigate. This study aims to design the UI/UX for a PasswordManager application named “Simpan Kunci” using the User-CenteredDesign (UCD) approach to ensure alignment with user requirements. TheUCD framework was applied through four structured phases: UnderstandContext of Use, Specify User Requirements, Produce Design Solutions, andEvaluate Design Against Requirements. Evaluation was conducted using theSystem Usability Scale (SUS) involving 20 respondents. The research yieldeda high-fidelity UI/UX design comprising password management, master passwordauthentication, search functionality, and account categorization featureswithin a clean, intuitive interface. Based on the SUS evaluation, an averagescore of 80.62 was achieved, falling into Grade B, Good adjective rating, andAcceptable category. These results demonstrate that the proposed UI/UXdesign for the Simpan Kunci application exhibits strong usability, is easyto understand, and effectively meets user needs in managing digital accountpasswords.]]>
