Abstract
Graphical user authentication (GUA) is a common alternative to text-based user authentication, where people are required to draw graphical passwords on background images. Recent research provides evidence that gamification of the graphical password creation process influences people to make less predictable choices. Aiming to understand the underlying reasons from a visual behavior perspective, in this paper, we report a small-scale eye-tracking study that compares the visual behavior developed by people who follow a gamified approach and people who follow a non-gamified approach to make their graphical password choices. The results show that people who follow a gamified approach have higher gaze-based entropy, as they fixate on more image areas and for longer periods, and thus, they have an increased effective password space, which could lead to better and less predictable password choices.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
