What is Two-Factor Authentication?

May 09, 2023

Two-factor authentication helps protect your information and prevent cyber attacks. Learn how services like Cox use 2FA to enhance security.


Two layers of security are better than one. That's why many digital services now require two-factor authentication for account access. When logging into your bank's website, for example, you might be asked to provide your password and a time-sensitive code sent to your mobile device. It might seem like an annoying, extra step, but it's worth the trouble to keep your data secure.


In 2022, Americans submitted over 800,000 cybercrime complaints, amounting to a potential loss of $10.2 billion — up from $6.9 billion in 2021. Two-factor authentication is an important security measure that can help prevent the risk of fraud and cybercrime.


Here, we'll outline what two-factor authentication is, how it works and how businesses like Cox use it to deliver safer, connected experiences.


What Are the Types of Two-Factor Authentication?

Two-factor authentication, also known as 2FA, two-step verification and multi-factor verification, is the process of requiring two different forms of information to verify a user. It adds an extra layer of protection, screening and security to the login process.


According to the National Institute of Standards and Technology, part of the U.S. Department of Commerce, there are three types of authentication factors:

  • Something you know, such as a password or PIN
  • Something you have, such as a code sent to your cell phone
  • Something you are, such as a fingerprint or face scan

For two-factor authentication, you typically have to provide a password or PIN, and either have a code sent to your phone or provide a fingerprint or face scan.


What Are Examples of Two-Factor Authentication?

Many online services use two-factor authentication to protect customer information. Facebook, for example, gives users the option of setting up two-factor authentication. With this feature enabled, you'll be asked to enter your password along with a login code sent to your mobile device or provided by a third-party authentication app.

Instagram also enhances safety by offering two-factor authentication through either an authentication app, text message code, or WhatsApp message. Twitter requires two-factor authentication for people who subscribe to their premium Twitter Blue service.


How Can You Secure Your Cox Account?

Cox offers two-step verification for its internet and mobile services — it's a requirement for Cox Mobile customers, as well as customers whose accounts were previously compromised.


It's easy to set up two-factor verification in just a few steps. Once it's done, you can sign into your Cox accounts with your password and a verification code sent via text, phone call, or email.


It's important to protect your information from potential cyber attacks and breaches. You can keep strengthening your passwords with capital letters, numbers, and special characters. But even with ironclad login information, two-step verification adds that extra layer of security to help keep your account safe.


Why Is Two-Factor Authentication Important?

Two-factor authentication helps protect your accounts and personal information from cybercriminals. Even if a hacker knows your password, for instance, they would still need another form of information to access your account.


Two-factor authentication can help prevent unauthorized users from signing into platforms under your name, potentially saving you money and a great deal of headache.
