lets check out the definition of OUT OF BAND Authentication.

Out-of-band authentication is a type of two-factor authentication that requires a secondary verification method through a separate communication channel along with the typical ID and password.

a communication request is sent from the terminal to a server on a first communication path. An image containing a series of symbols is communicated to the user on a communication path different from the first path.

two separate paths of authentication.. is in fact OUT OF BAND.
