With online security becoming a popular topic, the importance of implementing secure authentication methods on websites is more crucial than ever. By ensuring that your users’ information stays safely behind your website barriers is about more than just maintaining your users’ trust. Without the right security measures in place, your users’ accounts could be easily compromised.

As a result, sensitive information on users’ credit cards, contact information, and so much more could be in the hands of cybercriminals.

While many organizations aren’t quite comfortable with the idea of removing passwords entirely, there are additional measures they can use to ensure that cybercriminals can’t access users’ private information.

One solution? Two-factor authentication. 

You’ve probably heard this term mentioned when the question of password security is brought up, but what is two-factor authentication and how can it make your users’ accounts more secure?

You’re in luck! We’ll cover these questions and more in this in-depth look at two-factor authentication.

Feel free to read our entire guide, or jump down to the following questions you need answered: 

What is two-factor authentication?
How does two-factor authentication work?
Why should websites use two-factor authentication?
What types of two-factor authentication can websites implement?
How can organizations find a two-factor authentication vendor?
Before you get started, brush up on how website authentication normally works with our complete guide!

Keep reading to learn the ins and outs of two-factor authentication.

1. What is two-factor authentication?
Simply put, two-factor authentication, otherwise known as two-factor verification or 2FA, is an additional step in the login process that requires users to present a piece of information that only the user should have.

This “piece of information” can be anything from a one-time passcode to a physical token (for more types, jump to section four) that acts as a second confirmation to verify users are who they say they are.

Essentially, a true form of two-factor authentication requires the user to have:

A password and username (what they know)
A passcode that was sent to their mobile phone, email, or authenticator app (what they have)
