ABSTRACT:
A method and a system for authentication and synchronization is disclosed. The user provides a first one time code (OTC) to the authentication manager. If this OTC is within a small access window, the user is directly authenticated and granted access to the system. If the provided OTC is outside the small window but within a big window, the authentication manager saves the first OTC, and a second OTC is required from the user. If the new, second OTC and the first OTC are in sequence, the end user will be authenticated, and admitted access to the system and the requested service.
