Exploring the Impact of QR Codes in Authentication Protection: A Study Based on PMT and TPB

The fast growing usage of mobile devices to access services over telecommunication networks urges researchers to look for an efficient way to secure users’ online credentials. Rooted in online users’ fear appeals, this study measures the impact of an emerging use of technology, QR codes, on authentication protection. We contribute to the extant literature by integrating two theories—protection motivation theory and the theory of planned behavior, as well as investigating how the collaboration of computers and mobile devices enhances the protection of users’ online credentials. The results of the study additionally provide insights for IT developers for future directions in the development of authentication protection.
