DUO Two-Factor Authentication

What is Two-Factor Authentication (2FA)?

Two-factor authentication (2FA) is a specific type of multi-factor authentication (MFA) that strengthens access security by requiring two methods (also referred to as authentication factors) to verify your identity. These factors can include something you know – like a username and password – plus something you have – like a smartphone app – to approve authentication requests.2FA protects against phishing, social engineering and password brute-force attacks and secures your logins from attackers exploiting weak or stolen credentials.

Why is 2FA Important?

Two-factor authentication (2FA) is the foundational element of a zero trust security model. In order to protect sensitive data, you must verify that the users trying to access that data are who they say they are. 2FA is an effective way to protect against many security threats that target user passwords and accounts, such as phishing, brute-force attacks, credential exploitation and more.Let’s say you use a username and password to complete primary authentication to an application. That information is sent over the Internet (your primary network). You’ll want to use a different (out-of-band) channel to complete your second factor. Approving a push notification sent over your mobile network is an example of out-of-band authentication.

So why does it matter? If a remote attacker is able to tap into your computer via your Internet connection, they can steal your password, and your second form of authentication — if both are delivered over the same channel.Without your physical device, remote attackers can’t pretend to be you in order to gain unauthorized access to corporate networks, cloud storage, financial information, etc. stored in applications.By integrating two-factor authentication with your applications, attackers are unable to access your accounts without possessing your physical device needed to complete the second factor.

2FA Made Easy With Duo

We know the most effective security solution is one your users actually use. Duo’s 2FA solution only requires your users to carry one device — their smartphone, with the Duo Mobile app installed on it. Duo Mobile is available for both iPhones and Android, as well as wearables like the Apple Watch.
With support for a large array of authentication methods, logging in via push notification is fast and easy with Duo Mobile. We strongly recommend using Duo Push or Web Auth as your second factor, because they’re most secure and can protect against man-in-the-middle (MITM) attacks, but with Duo’s flexibility and customizability, you’ll be able to find the adaptive authentication method that meets the unique needs of your diverse user base.
