The serious issues which we face in the field of the information correspondence is the manner by which to share the information safely and in the event that the secured by the secret key, at that point the secret phrase will be of so strengthfull that the programmers won't ready to break that. So as to deal with these issues, the proposed idea is recommended. The proposed work execution is finished utilizing the PHP language and the database which is utilized for the administration of the clients and different intentions is made in MYSQL. In the proposed work, according to the base paper endeavors to counteract the speculating attack on the secret word , we have picked the new calculation which takes the utilization of the SHA-256 Hash age for upgrading the security of the secret phrase. The proposed work is an unadulterated blend of the graphical and text approach. In this we pick a 3 key methodology, wherein the client needs to initially choose the 3 pictures which can be pick by the client and can be any picture however the size limitations will be there

Data Security, OTP, Graphical Password, SHA-256.
