Research and editorial responsibility
Tobias Reittinger
Digital decisions, interface design and human-centred cybersecurity.
Tobias Reittinger researches how digital interfaces and incentive mechanisms influence user decisions, with a focus on digital nudges and human-centred cybersecurity. He studied Management Information Systems at the University of Regensburg. His research includes work published at ACM CHI and USENIX SOUPS, and a paper listed among the accepted papers at the IEEE Symposium on Security and Privacy 2026.
For Unfair Trading Australia, he brings this research perspective to explanations of consumer journeys, interface evidence and the distinction between Australian statutory tests and implementation questions.
Research perspective
Understanding a decision means examining the options, defaults, timing and consequences that a person encounters. Empirical research can help test explanations about behaviour. Legal analysis still requires the applicable rule, its scope and evidence of each element.

Moving Beyond Passwords: Investigating the Effect of Digital Nudges on Passkey Adoption
Tobias Reittinger, Magdalena Glas, Günther Pernul
Examines how the design and timing of digital nudges affect passkey adoption across user-journey touchpoints. This supports asking where an interface intervention occurs and how its behavioural effects are evaluated.
Publisher DOI: 10.1145/3772318.3791425
The paper received an Honorable Mention Award at CHI 2026. University award announcement.

No Password, No Problem? A Large-Scale Field Study of Passkey Adoption and Usage
Tobias Reittinger, Günther Pernul

These works concern cybersecurity and digital decisions. They are not studies of the Digital Fairness Act or Australian consumer law.
