How to Use Two-Factor Authentication To Protect Yourself Online

You probably already know that a strong password is the first step you can take for more protection online. A strong password is a simple change that can make a big difference. But you can take that protection one step further by using two-factor authentication in your other cybersecurity solutions logins

What is Two-Factor Authentication?

Two-factor authentication (2FA) requires two methods to verify your identity when signing into an account. It’s just one type of multi-factor authentication (MFA), which can require even more steps to access an account. 

Two-factor identification typically uses the usual method for account access, a username, and a password. Once those have been provided, another method is required, like receiving a text. 

While receiving a text is a common way to utilize two-factor authentication, it’s not one we recommend because of SIM-swap fraud. The best and most secure secondary method is a smartphone app to approve any sign-in requests. 

In general, people keep more and more sensitive information in accounts so keeping those accounts secure is more important than ever. 2FA, especially when an app is used, maintains an extra line of defense for your information. 

Do I Really Need 2FA?

You only need to start using two-factor identification if you want to decrease the risk of unauthorized access to your accounts. And everyone should want to decrease that risk. 2FA protects you from password brute-force attacks and phishing and keeps your account secure even if your credentials have been stolen.

Companies and individuals alike have started to integrate 2FA into their systems. Unsecured data is at risk of being accessed by fraudsters and scammers. Even password databases are at risk of being compromised, but 2FA protects your data even if that happens. 

Benefits of Two-Factor Authentication

  • Extra steps to verify identity equals a decreased risk of unauthorized access. Many hackers are looking for an easy win, so don’t give them one!
  • Simplify resetting your password. You should reset your password regularly, and using 2FA makes the process faster and easier. 
  • More secure data. The more secure your data is, the more secure you are. Two-factor identification is easy to set up, and simple to use, but it makes a big difference in your online security.
