Multi-Factor Authentication

You might not realize it, but you regularly use multifactor authentication, also known as two-factor authentication (2fa). When you swipe your debit card and are asked to enter your PIN code is a form of two-factor authentication? You must possess your card AND know your PIN code.

How Does Two-Factor Authentication Work?

Two-Factor authentication (2fa) , is widely used to add a layer of security to your online accounts. The most common form of 2fa when logging into an account is the process of entering your password and then receiving a code via text on your smart device that you need to either enter on to your account or a push notification if you're using a 2fa app on a smart device. 

The second layer in 2fa means a bad actor would need to steal your password along with your smart device in order to compromise your account.

The three types of authentication:

• Something you know: password, PIN, security question

• Something you have: phone, credit card, fob device

• Something you are: biometric fingerprint, retina, face, or voice
