The most universal computer authentication method is to use alpha numerical user names and passwords. This technique has been shown to have significant drawbacks. For example, users tend to pick passwords that can be simply guessed. Conversely, if a password is stiff to guess, then it is often tough to memorize. To tackle this setback, some researchers have urbanized authentication methods that use pictures as passwords. In this paper, we accomplish complete assessment of the obtainable graphical password techniques. We classify these techniques into two categories: recognition-based and recall based approaches. We discuss the strengths and boundaries of every scheme and mention the future study directions in this area. In this paper, we are conducting widespread assessment of existing graphical image password authentication technique. Also we are here proposing a new technique for graphical authentication moving towards rather advance we have been added some features like sending text to registered number and as well as registered email ids. so, in this way security is going to be increase more and more. For generating sms we are going to use some embedded devices like gsm modem. In this way we are going to increase the authentication of our application.
