Two Factor Authentication: What You Need to Know

By dani

Two factor authentication, or 2FA, is a type of multi factor authentication that improves the security of your digital accounts by requiring two factors to verify your identity.

These factors are usually split in two categories. Something you know, such as a username and password, and something you have, such as a physical token or a phone app.

Here are the most common types of multi factor authentication.

  • SMS codes
  • Phone calls
  • Email codes
  • Authentication apps
  • Hardware tokens
  • Fingerprint sensors
2 FA sign-in can send SMS codes

There’s a great variety of 2 factor authentication apps to choose from today, and some of them come with additional security features. For example, BodyGuard Mobile Security allows you to lock your apps with a pin but also includes tools such as a VPN and phone locator.

But how important is 2FA really? Let’s take a look.

Why Is Two Factor Authentication Important?

2 step verification safeguards your digital accounts from phishing, brute force attempts, social engineering, and much more.

You need it because it’s a more effective way of controlling access than simply protecting your personal data with a password. If someone hacks into a 2FA-protected account, they will still need the second access factor, such as an SMS verification code.

Without 2FA, your only defense against a hacker or cybercriminal looking to steal your personal information is a password.

  7. Pick the type of backup option (additional number or passcode) in case you lose your phone and click the “Next” button.
  8. Confirm that you want to turn on two factor authentication by clicking the “Turn on” button.

And voila, you just took your Google account’s security to the next level. Simple as that.

Your email can be a link to your entire online identity.
