Getting Started with Duo Security

Last Updated: May 5th, 2020


Add robust two-factor authentication to your VPN, email, web portal, cloud services, etc. with Duo. After successful primary authentication, your users simply approve a secondary authentication request pushed to our Duo Mobile smartphone app. Users may also authenticate by answering a phone call or by entering a one-time passcode generated by the Duo Mobile app, a compatible hardware token, or received via SMS.

Getting Started

To give Duo a try, just follow these steps:

  1. Sign up for a Duo account, which offers a free 30 day trial of our Access plan.

  2. Follow the steps on screen to configure two-factor authentication for your Duo administrator account.

  3. Add a backup phone number to your Duo administrator account.

  4. Use your new administrator account to log into the Duo Admin Panel.

  5. Decide which service, system, or appliance you want to protect with Duo. The Applications page lists all resources that are linked and protected by your Duo service.

    Then, use our documentation to configure the Duo application on your service, system, or appliance.

  6. Enroll your users in Duo. We provide several methods for enrollment, such as importing from an Active Directory domain. Some applications also support self-enrollment by users when they access the protected service.

    User Enrollment

    Your Duo administrator login can't also be used to log into the service or device now protected by a Duo application, so don't forget to enroll a user account for yourself!

  7. Start authenticating!
