This paper explores options for developing a cryptographic two-factor authentication protocol aimed at improving the security of user authentication in distributed information systems. The proposed approach integrates cryptographic mechanisms with a second authentication factor to strengthen resistance against credential theft, replay attacks, and unauthorized access while maintaining practical usability. The study outlines key design principles, evaluates potential implementation approaches, and discusses their applicability for modern cybersecurity environments.
