Two Factor Authentication

Two Factor Authentication (2FA) is a term used for the process of requiring a user to verify their identity in two unique ways to grant access to systems.

The technology is not new – it was conceived back in 1984. Loss of data can have dire consequences today more than ever, and so two-factor authentication protects against the threats of hacking and data theft. The account can not be accessed without knowing the method used as the second factor, and also having access to the second factor such as dynamically generated one-time password, SMS message, or biological token.

There are different ways to implement 2FA, and they all increase the security of user accounts, including SMS tokens.

SMS token authentication

This method is common, and involves a unique token being sent to the user via an SMS text message.
