Implement Java 2-Factor SMS Secure Login

I require a proficient Java developer who can create a login system utilizing two-factor authentication via SMS. Here's what's needed: - Develop a login system employing Java. You must demonstrate an understanding of programming practices and concepts in Java. - Implement two-factor authentication. The system should allow users to receive an authentication code via SMS which is necessary for the login process. Experience with incorporating SMS verification frameworks is preferred. - Please note, the system will not need to interface with any existing database. It should showcase secure login practices for educational use. - The project doesn't need a GUI at the moment as this is primarily aimed at being a code testing resource. Please, no newbies. This project requires someone who understands Java and two-factor authentication intimately.
