In recent times, data over the internet increased enormously. Authentication is the only technique available and used for accessing data. Cyber attacks are also growing immensely, so security is the primary concern for each person. People are worried about their email passwords, cloud passwords, ATM pins, and different site passwords. Textual passwords are the extensively seen procedure used for verification. However, textual passwords are powerless against modern-day attacks such as shoulder surfing attack, key loggers, spyware attack, and social engineering attack. OTP's, Biometric authentication, draw-a-secret, and Graphical passwords evolved as alternative methods for the Textual Passwords, but OTP's require the secure and reliable network connection mobile, Biometric authentication require separate hardware, draw-a-secret, and most of the graphical password techniques are defenseless to shoulder surfing attack. To overcome these problems here presenting a session password-based method PDGC: Passcode detection using the color grid. In this PDCS technique user needs to analyze and enter session passcode based on actual password with the help of color matrix grid displayed during login.
