ABSTRACT
The paper examined the design and implementation of a two-factor authentication login system using OTP with SMS. The ever-increasing use of internet around the world has without doubt increased the usage of internet-based services, e-business models, easier ways of communication and information sharing. Such drastic increase in usage of network-based systems has made the current cyber security systems old dated as the hackers and attackers of networked systems is on the rise with new and modern attack methodologies. This has necessitated the need of more secure ways of communications. The issues of Confidentiality, Integrity and the Availability of systems are of prime importance and more research towards these issues has been called for around the world. One of the major areas of security improvement is the way in which authentication of users is carried out. Even though many organizations still rely on static ID and password authentication system, this method is getting old and there is a requirement for a better way of authentication which is required. One of the solutions for this issue is the two factor authentication technique as a fundamental security function. Our thesis proposal explores the two factor authentication technique and implementation issues which can be used for the two factor authentication technique. Two-factor authentication method is implemented in two main phases. In the first phase, the authenticator gets a request generated by the application to authenticate a specified user. When the request is received, it generates a one-time password and sends it through a SMS to a GSM cell phone registered for that specified user. The one-time password has a default timeout 5 minutes which is configurable. In the second phase of the authentication, a request is sent with the user id and a hash of the one-time password. If both the one-time and user specified password is valid then the user will be authenticated. It proposes a secure, convenient and user friendly two factor authentication scheme and discusses its applications to online banking.

I actually googled and saw about projectmaster.com.ng, copied the number and contacted them through WhatsApp to ask for the availability of the material and to my luck they have it. So there was a delay with the project due to the covid19 pandemic. I was really scared before making the payment cause I’ve been scammed twice, they attended so well to me and that made me trust the process and made the payment and provided them with proof, I got my material in less than 10minutes.
I received excellent customer support, and quickly. Thank you so much!
I love your service! I would recommend projectmaster.com.ng to anyone. What a great find!
I am aware of online scam but because of the hectic nature of writing project, I decided to try sourcing for help online and to my surprise, projectmaster.com.ng gave complete project in less than 5 minutes. I could not believe it sincerely. Thank you so much guys.
