Multifactor Authentication (MFA)

What is MFA (Multi-Factor Authentication)?

Multi-factor authentication (MFA) is a security process that requires users to verify their identity using two or more independent factors before accessing an account, system, or resource.

• Something You Know: A password, PIN, or answer to a security question.

• Something You Have: A physical device like a smartphone, security token, or smart card.

For example, logging in with a password (something you know) and then entering a code sent to your e-mail on your phone (something you have) is a standard implementation of MFA.
