    Emerging Trends in Usable Security and Privacy
    (i-com: Vol. 18, No. 3, 2019) Alt, Florian; von Zezschwitz, Emanuel
    New technologies are constantly becoming part of our everyday life. At the same time, designers and developers still often do not consider the implications of their design choices on security and privacy. For example, new technologies generate sensitive data, enable access to sensitive data, or can be used in malicious ways. This creates a need to fundamentally rethink the way in which we design new technologies. While some of the related opportunities and challenges have been recognized and are being addressed by the community, there is still a need for a more holistic understanding. In this editorial, we will address this by (1) providing a brief historical overview on the research field of ‘Usable Security and Privacy’; (2) deriving a number of current and future trends; and (3) briefly introducing the articles that are part of this special issue and describing how they relate to the current trends and what researchers and practitioners can learn from them.

    “Get a Free Item Pack with Every Activation!” - Do Incentives Increase the Adoption Rates of Two-Factor Authentication?
    (i-com: Vol. 18, No. 3, 2019) Busse, Karoline; Amft, Sabrina; Hecker, Daniel; von Zezschwitz, Emanuel
    Account security is an ongoing issue in practice. Two-Factor Authentication (2FA) is a mechanism which could help mitigate this problem, however adoption is not very high in most domains. Online gaming has adopted an interesting approach to drive adoption: Games offer small rewards such as visual modifications to the player’s avatar’s appearance, if players utilize 2FA. In this paper, we evaluate the effectiveness of these incentives and investigate how they can be applied to non-gaming contexts. We conducted two surveys, one recruiting gamers and one recruiting from a general population. In addition, we conducted three focus group interviews to evaluate various incentive designs for both, the gaming context and the non-gaming context. We found that visual modifications, which are the most popular type of gaming-related incentives, are not as popular in non-gaming contexts. However, our design explorations indicate that well-chosen incentives have the potential to lead to more users adopting 2FA, even outside of the gaming context.
