Multi-Factor Authentication (MFA) 

Revision Date

Multifactor authentication is a layered approach to securing data and applications where a system requires a user to present a combination of two or more credentials to verify a user’s identity for login. MFA increases security because even if one credential becomes compromised, unauthorized users will be unable to meet the second authentication requirement and will not be able to access the targeted physical space, computing device, network, or database.
