TLDR
The results show that the graphical group took longer and made more errors in learning the password, but that the difference was largely a consequence of just a few graphical participants who had difficulty learning to use graphical passwords.Abstract:
Access to computer systems is most often based on the use of alphanumeric passwords. However, users have difficulty remembering a password that is long and random-appearing. Instead, they create short, simple, and insecure passwords. Graphical passwords have been designed to try to make passwords more memorable and easier for people to use and, therefore, more secure. Using a graphical password, users click on images rather than type alphanumeric characters. We have designed a new and more secure graphical password system, called PassPoints. In this paper we describe the PassPoints system, its security characteristics, and the empirical study we carried out comparing PassPoints to alphanumeric passwords. In the empirical study participants learned either an alphanumeric or graphical password and subsequently carried out three longitudinal trials to input their passwords over a period of five weeks. The results show that the graphical group took longer and made more errors in learning the password, but that the difference was largely a consequence of just a few graphical participants who had difficulty learning to use graphical passwords. In the longitudinal trials the two groups performed similarly on memory of their password, but the graphical group took more time to input a password.read more

Graphical passwords: a survey

TL;DR: This survey tries to answer two important questions: "Are graphical passwords as secure as text-based passwords?" and "What are the major design and implementation issues for graphical passwords?"

Authentication using graphical passwords: effects of tolerance and image choice
TL;DR: Results show that accurate memory for the password is strongly reduced when using a small tolerance around the user's password points, which suggests that many images may support memorability in graphical password systems.

Human-seeded attacks and exploiting hot-spots in graphical passwords

TL;DR: The results suggest that these graphical password schemes appear to be at least as susceptible to offline attack as the traditional text passwords they were proposed to replace.

Quantifying the security of graphical passwords: the case of android unlock patterns
TL;DR: This paper systematically improves the security of the Android Unlock Pattern by finding a small, but still effective change in the pattern layout that makes graphical user logins substantially more secure.

The information capacity of the human motor system in controlling the amplitude of movement.
TL;DR: The motor system in the present case is defined as including the visual and proprioceptive feedback loops that permit S to monitor his own activity, and the information capacity of the motor system is specified by its ability to produce consistently one class of movement from among several alternative movement classes.

Users are not the enemy

TL;DR: It is argued that to change this state of affairs, security departments need to communicate more with users, and adopt a usercentered design approach.
