An Exploration of Graphical Password Authentication for Children
This work addresses usability issues in authentication for children, though it is incremental as it builds on existing graphical password schemes.
The paper tackled the problem of creating child-friendly authentication by evaluating three PassTiles graphical password variants, finding that children recalled passwords with distinct object images most successfully and both children and adults preferred graphical passwords over existing schemes.
In this paper, we explore graphical passwords as a child-friendly alternative for user authentication. We evaluate the usability of three variants of the PassTiles graphical password scheme for children, and explore the similarities and differences in performance and preferences between children and adults while using these schemes. Children were most successful at recalling passwords containing images of distinct objects. Both children and adults prefer graphical passwords to their existing schemes, but password memorization strategies differ considerably between the two groups. Based on our findings, we provide recommendations for designing more child-friendly authentication schemes.
