How 2FA works To understand two-factor authentication, you first need to understand factors. A 2FA factor is what you will need to access the account, and they are generally broken into three categories: Knowledge: These factors require you to know something, like security questions, a PIN sent to your device, or a specific keystroke.

Possession: The user must physically possess the factor, like a debit card or a USB drive, and insert it into the device to gain entry. Biology: Access is granted once the user proves their identity through biological markers like a fingerprint or voice.

Hardware tokens: This type of 2FA requires users to possess a type of physical token, such as a USB token, that they must insert in their device before logging on. Some hardware tokens display a digital code that users must enter. Software tokens for 2FA: These tokens are apps that you download. Any site that features 2FA, will then send a code to the app that you enter before logging on. When you enter your login credentials to access a website, a push notification is sent to your smartphone.

A message will then appear on your phone requesting that you approve your log-in attempt with a tap. Most commonly, this means using a fingerprint scanner. Location: If your account was created and registered in one state, and suddenly a log-in is attempted in a different location, it may trigger a location factor. These factors will alert you when a log-in is attempted on a new device and send you a code to enter to verify your identity. How to enable 2FA Though not all sites use 2FA, some give you the option to activate it for your account.
