Vulnerability text password were well known. Users tend to choose short passwords or passwords that are easy to remember, which makes passwords are vulnerable to attackers to break. In addition, text password is vulnerable to shoulder-surfing, a hidden camera and spy attacks. Graphical schema password has been suggested as a possible alternative to the textual schema. However, for the most part, they are vulnerable to shoulder-surfing. In this article we offer Scalable shoulder-Surfing Resistant alphanumeric picture password authentication scheme (S3PAS). S3PAS integrates text and graphical schema password and provides nearly ideal resistant to shoulder-surfing, a hidden camera and spy attacks. It can replace or coexist with traditional systems text password without changing the user's existing profile password. Moreover, it is not immune to brute-force attacks through dynamic and volatile session passwords. S3PAS shows the considerable potential of bridging the gap between a plain text password and password. Further improvements of S3PAS scheme proposed and briefly discussed. Theoretical analysis of the level of safety with the help of S3PAS also studied.
