Authentication that requires utilizing a separate network for transmission of identification factors is considered out-of-band. An example would be during two-factor authentication when a user logs into an online banking account. When a bank account holder logs into the banks website from their home computer with traditional login credentials a one-time password may be delivered to their mobile phone through SMS text message. This mobile OTP is an out-of-band authentication solution because it utilizes the cellular phone company’s network for transmission as opposed to the network which established the connection.
