How does multi-factor authentication work?
Multi-factor authentication works by requesting multiple forms of ID from the user at the time of account registration. The system stores this ID and user information to verify the user for next login. The login is a multi-step process that verifies the other ID information along with the password.
What combination of authentication factors will qualify as multifactor authentication?
Multifactor authentication combines two or more independent credentials: what the user knows, such as a password; what the user has, such as a security token; and what the user is, by using biometric verification methods.
What is an example of multi-factor 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.
