Abstract: In the today’s world with the remarkable development in computer system, single factor authentication, is no more examined as secure way to protect our confidential data. It is very simple and easy to guess passwords most often, they are short and based on subjects close to the user birthdays, partner names, children’s names and they are typically only letters and can be found via the secret key gathering programs. Multifactor authentication guarantees a higher level of protection by extending the single authentication factor. Authentication is basically the process of verifying the identity of a user. Our proposed idea focuses on the implementation of multifactor authentication methods by using OTP password and image based Password and question based password as gateway for authentication. An attempt has been made to provide extra layers of security by adding additional passwords.
