b) Multi-factor Authentication (MFA)
c) Biometric Authentication
d) Two-Factor Authentication (2FA)

Answer 1

Multi-factor Authentication (MFA) is the term used to describe two or more authentication methods used to authenticate someone. It is a security measure that requires users to provide multiple pieces of evidence to verify their identity.

Step-by-step explanation:

Multi-factor Authentication (MFA) is the term used to describe two or more authentication methods used to authenticate someone. It is a security measure that requires users to provide multiple pieces of evidence to verify their identity. This can include something they know (such as a password), something they have (such as a phone or token), or something they are (such as a fingerprint or facial recognition).

For example, when logging into an online banking account, a user may be required to enter a password (something they know) and provide a code sent to their mobile phone (something they have) to complete the authentication process.

Two-Factor Authentication (2FA) is another term often used interchangeably with MFA. However, 2FA specifically refers to using two distinct factors from different categories of authentication, while MFA can involve more than two factors.
