This document discusses 3D passwords as a multifactor authentication scheme. It outlines different types of existing authentication schemes like knowledge-based, token-based, and biometric-based schemes. It also describes the functional requirements and design guidelines for a 3D password system, including applications in critical systems. The document analyzes the security of 3D passwords and discusses potential attacks and countermeasures.

- 8. APPLICATIONS Critical servers. Nuclear and military facilities. Airplanes and jetfighters. ATMs, PDA’s, desktop computers and laptops.
- 9. SECURITY ANALYSIS 3D Password Space Size. 3D Password Distribution Knowledge.
- 10. CONCLUSION Commonly used authentication schemes are vulnerable to attacks. 3D Password is a multifactor authentication scheme. Design of 3D virtual environment, selection of objects inside the environment, and the object type reflects the resulted password space. User’s choice and decision to construct the desired and preferred 3D password
