Why Your Business Needs Two-Factor-Authentication (2FA): A Complete Guide

What is Two-Factor Authentication?

Two-factor authentication (also known as “two-step verification”) is an authentication method that requires two different “factors” to prove you are who you say you are. These factors could be something you have, such as a security token, a code from an app on your phone, or something you know, like a PIN or password. Two-factor authentication makes it harder for hackers to break into user accounts because they would need to have more than just a username and password to access the account. The two “factors” of authentication can be used at the same time or separately. For example, you could use two different app-based authentication tools that require you to scan a QR code with your phone and input a six-digit code. In this scenario, you would use both factors for authentication.

What is the difference between two-step verification and two-factor authentication (2FA)?

The primary difference between two-step verification and two-factor authentication is that the first is a specific type of authentication method, while the latter is a type of authentication method. In other words, two-step verification is one specific form of two-factor authentication. Specifically, it’s a verification method in which you have to enter some combination of a user ID or password and a randomly generated code that’s either sent to you via text or generated by an app on your phone. Two-factor authentication, on the other hand, is any form of authentication in which two factors are required to prove you are the legitimate user of a system.

Why Does Your Business Need Two-Factor Authentication?

There are many reasons why every company should use two-factor authentication, including: - Increased security - The biggest reason to use two-factor authentication is to increase security. Hackers will try to get your login information, but two-factor authentication makes it harder for them to break into your account. - Convenience - Because two-factor authentication requires you to enter two things to log in, it’s more secure than just using a password. However, it’s also more convenient because you don’t have to remember two separate passwords the way you have to with two-step verification. - Reduce the risk of account takeover - Two-factor authentication can also help reduce the risk of account takeover, or when a hacker successfully logs into your account and changes your login information. - Stay compliant with regulations - Businesses that handle sensitive customer data, like banks, healthcare providers, and social media platforms, are required to use two-factor authentication. Many other industries also need two-factor authentication to stay compliant with regulations.

Examples of Two-Factor Authentication

There are many different types of two-factor authentication. Some common examples include: - SMS or Text Authentication - This is the most common form of two-factor authentication. When a user attempts to log in, they enter their credentials and receive a code via text. They then enter that code to log in. - Authenticator Apps - These apps generate a code that changes every 30 seconds and are used to log in. Authenticator apps include Google Authenticator and Authy. - Token-based Authentication - This authentication method uses a physical device that generates a “token”, which is a unique digital string that changes every 30 seconds. - Biometric Authentication - This is a two-factor authentication method that uses physical attributes like DNA, fingerprints, or retina patterns to identify a user. - Voice Authentication - This two-factor authentication method uses your voice to log in. - Virtual Token Authentication - With virtual token authentication, you install an application on your computer and use a generated token displayed on your screen. - Biometric Security Tokens - These security tokens are physical devices that generate a one-time authentication code. - Public Key Authentication - This authentication method uses a combination of a public key and a private key to log in.

How to Implement Two-Factor Authentication

First you’ll need to decide which type of two-factor authentication you want to use. Then you can use this information to decide which authentication tools you should use. Once you’ve selected the tools you plan to use, you’ll need to decide how they will be implemented throughout your business. - Decide on a type of two-factor authentication - You can use a variety of two-factor authentication methods, including text messages, authenticator apps, and security tokens. - Select authentication tools - Once you’ve decided on a type of two-factor authentication, you can select the tools that will help you implement it. - Select login methods - Authentication tools can be used for more than just logging in. You can also use authentication tools to sign up for an account, reset your password, and log out of accounts. - Determine how authentication will be enforced - Some authentication methods, like security tokens, can be used with more than one login method. Other authentication methods, like text messages, can only be used for logging in.

Tips for Running a Successful Two-factor Authentication Program

There are plenty of ways to implement two-factor authentication, but there are also plenty of ways to mess it up. If you want to make sure your two-factor authentication program is successful, keep these tips in mind: - Pick a type of two-factor authentication and stick with it. It’s tempting to pick a different method each time you roll out two-factor authentication. But if you do, it will be much more confusing for users to figure out which login method to use. - Don’t use two-factor authentication as the only login method. While two-factor authentication can significantly increase security, it’s not a complete replacement for passwords. Instead, use it to complement passwords and log in and sign up for accounts. - Keep track of login statistics. You should know how many people are logging in and how they’re logging in. If you notice an increase in login attempts, that’s a sign you may need to increase the security of your two-factor authentication. - Test your two-factor authentication. It’s important to test your two-factor authentication to make sure it works for the people who need it.
