What is a Multifactor Authentication (MFA)?
What is MFA?
Multifactor Authentication (MFA) is the use of two or more authentication factors. MFA is successfully enabled when at least two of these categories of identification are required in order to successfully verify a user’s identity prior to granting access.
Something you know:
A password or passphrase is something you know.
Something you have:
A token or smartcard is something you have.
Something you are:
Biometric identification through a fingerprint or retina scan establishes something you are.
There is flexibility regarding which authenticators are used by a business to validate a user’s identity without undue inconvenience.
