Final answer:

Multifactor authentication, which enhances security, typically involves using a combination of knowledge factors like passwords and possession factors such as a mobile device with a security app.

Step-by-step explanation:

Multifactor authentication (MFA) is a security system that requires more than one method of authentication from independent categories of credentials to verify the user's identity for a login or other transaction. Two common types of multifactor authentication include:

  • Knowledge factors: Something the user knows, such as a password, PIN, or answers to "secret questions."
  • Possession factors: Something the user has, like a security token, a smartphone app that generates a time-based one-time password (TOTP), or a text message with a code sent to the user's phone.

By implementing both factors, users can benefit from an increased level of security which helps protect against unauthorized access to accounts and sensitive information.
