Answer 2

Answer:

Multi-factor authentication (MFA; encompassing Two-factor authentication or 2FA, along with similar terms) is an electronic authentication method in which a device user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something only the user knows), possession (something only the user has), and inherence (something only the user is). MFA protects the user from an unknown person trying to access their data such as personal ID details or financial assets.
