Recognizing that users often perceive security as an obstacle to achieving their goals, this research emphasizes the integration of usability and security as complementary features rather than conflicting tradeoffs. This study explores the implementation of Double-Patterns (D-Patts) by J. Forman et al, an approach that requires users to create two patterns instead of one for enhanced security. Findings indicate that users frequently select symmetric patterns, prompting the introduction of background images to encourage the creation of asymmetric patterns. Further recommendations include implementing blocklists for commonly used patterns and adjusting the position of the grid on the screen to improve security and usability.49enUsable securityAuthentication methodsDouble-patternsSecurityInformatics::Computer ScienceHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
