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. Voice recognition and fingerprint are both "something you are" so they are likewise only one factor. The three possible factors are something you are, something you have, and something you know. EDIT: But why does twitter call it 'two factor authentication' when it's a password + sms to phone? EDIT: The phone can technically be something only you should have.

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.
Which of the following are examples of multi-factor authentication? ›These are a few examples of such authentication factors:
- Fingerprint scans.
- Retina scans.
- Voice recognition.
- Facial recognition.
- Behavioral biometrics like keystroke dynamics.
The three most common kinds of factors are:
- Something you know - Like a password, or a memorized PIN.
- Something you have - Like a smartphone, or a secure USB key.
- Something you are - Like a fingerprint, or facial recognition.
Something you know would be a password, a PIN, or some other personal information. Something you have would be a one-time-use token, a smartcard, or some other artifact that you might have in your physical possession. Something you are would be your biometric identity like a fingerprint or a speech pattern.
What is a multi-factor authentication quizlet? ›What is multifactor authentication? requires more than two means of authentication such as what the user knows (password), what the user has (security token), and what the user is (biometric verification)
What are three examples of two-factor authentication? ›The Now: What is Two-Factor Authentication?
- Something you know, like a password or PIN.
- Something you have, like your ATM card, or your phone.
- Something you are, like a fingerprint or voice print.
3FA: Example 1. Your password is qwerty and you have a YubiKey Bio security key. You use these two authentication methods together to log in to your account. Incidentally, YubiKey Bio is a security key that supports fingerprinting, which satisfies two authentication factors: something you have and something you are.
What 3 methods of multi-factor authentication are supported? ›Three Main Types of MFA Authentication Methods
- Things you know (knowledge), such as a password or PIN.
- Things you have (possession), such as a badge or smartphone.
- Things you are (inherence), such as a biometric like fingerprints or voice recognition.
For example, employees who work from home or are on the road may need to access company resources, such as email inboxes or internal databases. To secure these resources, the company can implement MFA, requiring the employee to provide a password and a one-time code sent to their mobile phone, for example.
What is not an example of multi-factor authentication? ›Voice-print authentication is not considered multi-factor authentication.

The primary objective of multi-factor authentication is to reduce the risk of account takeovers and provide additional security for users and their accounts. Since over 80% of cyber breaches happen due to weak or stolen passwords, MFA can provide added layers of security necessary to protect users and their data.
Which of the following is an example of three-factor authentication? ›Three-factor authentication
For example, a user trying to access a system using 3FA will have to provide something they know (username and password), something they have (fob or phone), and something they are (fingerprint or retina scan).
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).
Which of the following are multi-factor authentication factors? ›Which of the following constitutes multifactor authentication (MFA)? "Correct Answer: Username + password device PIN. MFA uses multiple categories of authentication such as something you know (username, password) along with something you have (a device on which you receive a PIN).
Which is an example of what you have in multifactor authentication? ›As an example of multi-factor authentication, imagine you are at an ATM so that you can withdraw money from your bank account. Your debit card (something you have) is one authentication factor. However, to access your account, you also need to enter the PIN that is associated with your debit card.
What is the 4 factor authentication? ›Four-factor authentication (4FA) is the use of four types of identity-confirming credentials, typically categorized as knowledge, possession, inherence and location factors. Four-factor authentication is a newer security paradigm than two-factor or three-factor authentication.
What is an example of multimodal authentication? ›A multimodal authentication system utilizes multiple biometric identifiers to verify a user's identity. These identifiers can be physiological (fingerprint, iris) or behavioral (voice, gait).
