During multi-factor and two-factor authentication processes a device may be used for one time password generation or OTP transmission. Known as an authentication token and ranging from a proprietary device to a regular mobile phone these tokens are used for out-of-band authentication. Many times when discussing the cost of authentication security the token is mentioned due to the costs associated with hardware creation and network expenses. Downsides to tokens are that they can be misplaced, stolen or broken.
