Dual code authentication system
摘要:
A verification method and system are disclosed that verify a user. The user is provided a verification code via, for example, a website, to be communicated to a provided electronic contact via a secondary mode of communication, such as through an SMS-enabled device. If the correct verification code is communicated by the user, the user receives a return message (e.g., a return SMS message) containing a second verification code, which the user submits to a website or on-line form or to another verification system for authentication.
