Question

a) One
b) Two or more

Answer 1

Multi-factor authentication (MFA) provides additional security for identities by requiring two or more authentication elements.

Step-by-step explanation:

Multi-factor authentication (MFA) provides additional security for identities by requiring two or more authentication elements.

MFA adds an extra layer of protection by combining multiple factors for identity verification. These factors can include something the user knows (like a password), something the user has (like a smartphone or a security token), or something the user is (like a fingerprint or facial recognition).

For example, when logging into an online account with MFA enabled, the user may be asked to enter a password and also provide a verification code sent to their smartphone. This way, even if someone gains access to the password, they would still need the additional verification code to complete the login process.
