Backup authentication is a crucial yet often overlooked problem in cybersecurity. Passwords and other methods of authentication are fixtures of digital life, but the processes by which we recover our passwords and other authentication methods are less well understood or studied. This research will focus on making backup authentication more secure by going beyond the conventional methods, including comprehensively designing and studying “social authentication” systems, which allow users to authenticate by leveraging their social networks.
