See Why Companies Should Use Two-Factor Authentication (2FA) and Especially 2FA from DUO Security


Benefits of Using 2FA

  1. Enhanced Security: 2FA adds a second layer of protection in addition to the regular password, making it much more difficult for attackers to access protected accounts, even if they manage to obtain the password.
  2. Prevention of Unauthorized Access: Even if an attacker obtains a user's password, they will not be able to access the account without the second authentication factor (e.g., a code sent to the phone).
  3. Reduced Phishing Risk: 2FA makes phishing attacks less effective because simply obtaining the password is not enough to compromise an account.

        Two-Factor Authentication (2FA) with Duo Security Involves Several Steps


        Here is a general description of the process:

        Step 1: Installing and Configuring the Duo Mobile App

        • Downloading the App: Install the Duo Mobile app on your mobile device. The app is available on the App Store (for iOS) and Google Play (for Android).
        • Initial Setup:
          • Open the app and allow notifications.
          • The app will prompt you to scan a QR code that you will receive from your system administrator or via an activation email.

        Step 2: Enrolling the Device in Duo

        • Receiving the Activation Invitation:
          • You will receive an email or message with an activation link or QR code from your organization's system administrator.
        • Scanning the QR Code:
          • Open the Duo Mobile app and select the option to add a new account.
          • Scan the received QR code.

        Step 3: Using Duo Security Authentication

        • Connecting to the Service:
          • Access the service or application that uses Duo for authentication (e.g., an email portal, VPN, etc.).
        • Entering Credentials:
          • Enter your username and password for your account as usual.
        • Duo Prompt:
          • After entering your credentials, you will be redirected to the Duo authentication screen.
          • You have several options to complete the authentication:
            • Push Notification: The Duo Mobile app will send a push notification to your phone. Approve the request to complete the authentication.
            • Verification Codes: The Duo Mobile app can generate a temporary code for you to enter on the authentication interface.
            • Phone Call: Duo can call your registered number, where you will confirm the authentication.
            • Text Message (SMS): You can receive a verification code via SMS.

        Step 4: Confirming Authentication

        • Approval/Code Entry:
          • Depending on the chosen method, either approve the push notification or enter the generated/received code.
        • Access to the Service:
          • After confirming the authentication, you will have access to the desired service or application.

        Additional Configurations

        • Adding Multiple Devices:
          • You can enroll multiple devices (e.g., phone and tablet) for redundancy.
        • Account Recovery:
          • In case of device loss, contact your system administrator to reset the 2FA authentication.

        Duo Security also provides detailed documentation and video tutorials for configuring and using the service, which can be very useful for users and administrators.
