Answer: multifactor authentication requires the user to provide two factors to gain entry to a resource. The first factor is generally a password or something that the user knows. The second factor is often something that the user possesses such as a token with a randomized number generator.

What is considered multi-factor authentication?

Multi-factor authentication is when a user must provide two or more pieces of evidence to verify their identity to gain access to an app or digital resource. Multi-factor authentication (MFA) is used to protect against hackers by ensuring that digital users are who they say they are.

What is multi-factor authentication used for?

MFA, sometimes referred to as two-factor authentication or 2FA, is a security enhancement that allows you to present two pieces of evidence – your credentials – when logging in to an account.

What is an example of a Web application using multi-factor authentication?

Examples of Something the User Has

A multi-factor authentication example of something the user has could include: Google Authenticator (an app on your phone). SMS text message with a code. Soft token (also called software token).

Which of the following is an example of multifactor authentication?

Of the alternatives given, only smart card plus PIN is an example of multi-factor authentication. A smart card is something you have; a PIN is something you know. Passwords are also something you know, so password plus PIN is still only one factor authentication.

When did multi-factor authentication start?

The Emergence and Adoption of 2FA. Though there have been several predecessors to the modern day two-factor authentication system, the 2FA that we would recognize today was first made commercially available by the RSA company as a key fob in 1986.

What is MFA and 2FA?

Multi-Factor Authentication (MFA) is a type of authentication that requires two or more factors of authentication. Two-Factor Authentication (2FA) is a type of authentication that requires exactly two factors of authentication. Every Two-Factor Authentication is Multi-Factor Authentication.

What is multifactor authentication quizlet?

Multifactor Authentication. A system that requires users to confirm their identities in two or more ways.

Which of the following is an example of multifactor authentication quizlet?

Multifactor means that more than one type of authentication is needed; for example, a fingerprint and a PIN.

What is not an example of multi-factor authentication?

Fingerprints, facial recognition, iris scans and handprint scans. It should be emphasised that while requiring multiple examples of a single factor (such as needing both a password and a PIN) does not constitute MFA, although it may provide some security benefits over a simple password.

What is the difference between multi-factor authentication and single factor authentication quizlet?

What is the difference between multifactor authentication and single-factor authentication? ANSWER: Multifactor authentication uses multiple types of authentication credentials, such as what a user knows and what a user has, whereas single-factor authentication uses only one type of authentication.

What are the two most commonly used authentication factors in multifactor authentication?

Authentication using two or more factors to achieve authentication. Factors include: (i) something you know (e.g. password/personal identification number (PIN)); (ii) something you have (e.g., cryptographic identification device, token); or (iii) something you are (e.g., biometric). See authenticator.

What are the two most commonly used authentication factors in multifactor authentication choose two?

Two-factor authentication methods rely on a user providing a password as the first factor and a second, different factor — usually either a security token or a biometric factor, such as a fingerprint or facial scan.

How do you use multi-factor authentication?

On the desktop, you access it by going to Settings > Security and Login. Under Two-Factor Authentication, click Edit on the right. On the next screen, select how you’d like to receive your second form of authentication: a text message, authenticator app, or physical security key.
