Password authentication is one of the most important components for security and confidentiality of data that is stored on various workstations and servers. There are various kinds of ways to authenticate passwords, for example, textual passwords, graphical passwords, session passwords etc. Biometric authentication is also one of the trending ways these days but has several physiological issues. Though textual password is very common among people, it is still susceptible to various attacks like brute force attacks, dictionary attack, glossary attack, shoulder surfing, keylogger attack or eavesdropping. Graphical passwords were the new solution but had drawbacks like taking more time to authenticate and slow processing issues. Thus we introduce a new session password system, which is a one-time use password. This system uses only symbols for authentication. The generation of the password each time depends on an algorithm.
