“…Privacy nudges entail people having a choice between two fairly equivalent options and the nudge persuades them to choose the wiser option (Choe et al, 2013;Jeske et al, 2014). Nudging in authentication does not match this pattern of use.…”

Nudging folks towards stronger password choices: providing certainty is the key

Persuading people to choose strong passwords is challenging. One way to influence password strength, as and when people are making the choice, is to tweak the choice architecture to encourage stronger choice. A variety of choice architecture manipulations (i.e. 'nudges') have been trialled by researchers with a view to strengthening the overall password profile. None has made much of a difference so far. Here, we report on our design of an influential behavioural intervention tailored to the password choice context: a hybrid nudge that significantly prompted stronger passwords. We carried out three longitudinal studies to analyse the efficacy of a range of 'nudges' by manipulating the password choice architecture of an actual university web application. The first and second studies tested the efficacy of several simple visual framing 'nudges'. Password strength did not budge. The third study tested expiration dates directly linked to password strength. This manipulation delivered a positive result: significantly longer and stronger passwords. Our main conclusion was that the final successful nudge provided participants with absolute certainty as to the benefit of a stronger password and that it was this certainty that made the difference.

“…Wilson et al studied the effect of predetermined privacy profiles to assist users with location sharing disclosures [30]. Choe et al investigated the impact of the "framing" heuristic (i.e., people would prefer alternatives that are framed as gains over those framed as loses, even when the two alternatives are equivalent) in the context of mobile apps selection; and found that the framing effect had minimal impact on participants' trust perceptions [10]. A recent longitudinal Facebook study highlighted how profoundly Facebook interface changes can impact users' information sharingindicating a potential for Facebook privacy nudges [23].…”

Anecdotal evidence and scholarly research have shown that Internet users may regret some of their online disclosures. To help individuals avoid such regrets, we designed two modifications to the Facebook web interface that nudge users to consider the content and audience of their online disclosures more carefully. We implemented and evaluated these two nudges in a 6-week field trial with 28 Facebook users. We analyzed participants' interactions with the nudges, the content of their posts, and opinions collected through surveys. We found that reminders about the audience of posts can prevent unintended disclosures without major burden; however, introducing a time delay before publishing users' posts can be perceived as both beneficial and annoying. On balance, some participants found the nudges helpful while others found them unnecessary or overly intrusive. We discuss implications and challenges for designing and evaluating systems to assist users with online disclosures.

“…A lot of private and often sensitive information about users that is collected through ubiquitous devices can be shared with unknown entities at any time, without them being aware. In order to control which of their personal data is being collected, who can collect such data, and when this is allowed, users currently need to go through and pre-set privacy rules for devices/applications they want to use [2,11,12]. Even then, controlling the diffusion of such information has become an increasingly daunting task, especially due to the innumerable possibilities of information flow and varying privacy preferences of users across different contexts.…”
