Abstract
A system and method for authentication a user attempting access to a service is disclosed herein. When a user attempts to gain access, a client associated with the user generates a unique authentication code that is stored at a callback server associated with the client. The user accesses an authentication server associated with the service and provides the authentication server with standard login credentials. The authentication server also obtains the authentication code from the user. If the authentication server successfully verifies the user's credentials, then the authentication server transmits a code validation request to the callback server to validate the authentication code. The callback server verifies that the received code matches a stored code and is current, and then issues a reply message to the authentication server. The authentication server grants or denies the user's access request based on the reply.
