This Paper describes a method of Implementing Two Factor Authentication Using Mobile Phones. The Proposed Method Guarantees that authenticating to services, such as Online machines or ATM machines is done in a very secure manner. The generated One Time Password is valid for only a short user defined period of time and is generated by factors that are unique to both, the user and the mobile device itself. Additionally, an SMS-based mechanism is implemented as both a backup mechanism for retrieving the password and as a possible mean of synchronization. The proposed method as been implemented and tested. Initial results show the success of the proposed method.
