Overview#Multiple-channel Authentication (MCA) is a method of Multi-Factor Authentication where one or more the Authentication Factors involved are communicated over separate communication channels or protocols.
The concept is that an Attacker would be challenged to determine:
- which channels are being used
- the timing differences of the separate channels would be more difficult to intercept
- requires knowledge on determining the weakness of each channel
