What is MFA?
A security mechanism is characterised as requiring a person to provide two or more credentials in order to authenticate their identity. By leveraging multiple credentials instead of one, even if one of the authentication factors is compromised, the authentication process can remain secure.
Factors for authentication refer to the various ways through which a user can authenticate their identity. These factors include expertise, knowledge, and possession, inherence, place and time
Key point:Multi-factor authentication's primary advantage is that it offers extra security by adding layer protection.
