The Effectiveness of Video Messaging Campaigns to Use 2FA

摘要

For exploring messaging campaigns that motivate users to adopt a new security behavior and affect their security decisions, we designed different informational videos asking users to adopt Duo Two-Factor Authentication (2FA) on their university account. These videos used five different communication techniques: Authoritarian, Logic, Benefit, Personal Risk, and Enterprise Risk. During the two weeks of the messaging campaigns, our preliminary results showed that no significant, differences were found between the treatment groups and the control group regarding adoption rate of Duo. However, we found that Authoritarian (20% of university employees enabled Duo 2FA on their university accounts) and Benefit (17%) had the highest percentages in enabling Duo 2FA compared to other groups. All groups stated that Duo 2FA is annoying but not difficult to use. In addition, we identified a preliminary list of improvements in the messaging design. Our findings suggest that including the improvements in the messaging will increase users' willingness to adopt new security features.
