    TodayâTMs many password schemes easily get attack by shoulder surfing or guessing the password. To overcome this many password schemes have been developed to oppose the shoulder surfing attack. However in todays world most of the people are familiar with textual password then graphical password scheme so many text-based graphical password schemes have been proposed. But none of this existing password scheme is efficient as well as secured. So in our paper we are proposing efficient as well as improved shoulder surfing resistant graphical password scheme by using different colors combination. In our scheme any user can easily and efficiently login the system without using any physical keyboard or onscreen keyboard. We also analyze the security and usability of our system we also show the resistance of our system to shoulder surfing attack as well as accidental login. In our system we are also using the concept of OTP generation and for generating the OTP we are using randam function code this is time based make our system database more secure.
