Graphical passwords
Graphical passwords are an alternative means of authentication for log-in intended to be used in place of conventional password; they utilize images instead of text. In many implementations, the user is required to pick from a series of images in the correct sequence in order to gain access.
While some believe that graphical passwords would be harder to crack, others suggest that people will be just as likely to pick common images or sequences as they are to pick common passwords.[citation needed]
