You can take several simple steps to enhance your system's security. For instance, you can implement strong passwords and encryption. Additionally, you could implement a Zero Trust Network Access (ZTNA) model, which is widely recognized as a standard commercial approach for providing secure access to networks and applications.

However, we should first discuss one of the most important tools available: Two-Factor Authentication (2FA). When used correctly, 2FA can significantly enhance your system's overall security.

The question is, do you need it?

What Is Two-Factor Authentication?

Even if you or your organization doesn't already use two-factor authentication, you're no doubt familiar with it by now.

The basic principle of two-factor authentication is this:

Merely entering your username and password (single-factor authentication) isn't enough. In addition, a second factor, like a randomly generated code sent to your phone, is deployed. Usually, this second factor requires authentication through another device, such as a cell phone, where SMS, email, and applications can verify your credentials.

When done right, two-factor authentication is an incredible option that offers two distinct benefits:

1. A second layer of authentication allows for better overall security from "brute force" attacks. Brute force attacks are when hackers run programs that attempt thousands of password and username combinations to gain access to a given account.
2. It's a great example of Zero Trust Security. Like any Zero Trust system, it assumes that people make mistakes—and prepares for people's mistakes.

It sounds great, right? Well, in many ways, 2FA is great, especially for customers.

But there are also potential downsides...

The Risks Of Two-Factor Authentication

The main risk with 2FA is hackers' ability to spoof SMS text messages. This technique allows hackers who have your password and phone number to intercept 2FA messages sent to your phone.

Though this is highly unlikely, you're probably safer using an integrated app rather than a phone number. Instead of an SMS message, an authenticator app randomly generates a number that's only usable for 30–40 seconds.

The use of 2FA also poses risks related to user experience and potential errors. For example, 2FA often requires end users to have a specific second device available, increasing their likelihood of getting locked out of their accounts.

The Benefits Outweigh The Risks

2FA is easy to set up, and the overall security benefits far outweigh any costs. Especially if you work with sensitive data, 2FA is an unquestionably strong security choice.

The benefits to customers and the overall increase in your security are well worth the cost. Not only do your customers know that you're taking the security of their data seriously, but you're also giving them peace of mind.

So, should you adopt Two-Factor Authentication?

The answer is unequivocally yes, especially if you have sensitive data.

Whether you're using an SMS service or integrating your system with an authenticator app, 2FA is well worth the cost of implementation. Your customers will not only thank you, but they'll trust your company over other companies. In a world where massive embarrassing data breaches happen without warning, certainty isn't something that you can put a price tag on.
