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.
With our free 30-day trial of our Duo Advantage plan, you can see for yourself how easy it is to get started with Duo's trusted access.
Your Duo Advantage trial comes with most of the features and functionality of a paid Duo Advantage subscription, with a few exceptions.
New Duo customer accounts don't automatically receive voice telephony. That means you won't be able to use phone calls as a two-factor authentication method for both administrators and end-users. Duo Push, SMS passcodes, security keys, and hardware tokens all remain available.
You also won't be able to make these user messaging customizations:
If you require telephony or customized email and SMS messaging as part of your Duo evaluation or subscription, please contact your Duo sales executive or Duo Support.
During your 30-day Advantage trial, you may choose to explore Duo Premier edition instead. To convert your Duo Advantage trial to a Duo Premier trial, visit the Billing page in the Duo Admin Panel once you've logged in and click Try It Free under the Duo Premier plan description.
When your Duo Advantage trial ends, your account switches to the Duo Free plan automatically. You can continue using your Duo Free plan for up to 10 users at no cost. Paid features you enabled during your trial no longer have any effect. If you convert this free account to a paid subscription, we'll restore the settings created during the trial.
To give Duo a try, just follow these steps:
Visit the Duo account signup page and enter your information to create an account.
Check your Inbox for a signup confirmation email from Duo. Click the Verify Email link in the message to continue setting up your account.
Follow the steps on-screen set a password for your Duo administrator account. Your admin username is the email address you used to sign up for Duo.
Install Duo Mobile on your Android or Apple smartphone and scan the barcode shown on-screen to activate Duo Push two-factor authentication for your Duo administrator account.
If you don't have an Android or Apple smartphone, click the link below the barcode to skip to the next step.
Set a backup phone number to your Duo administrator account. We'll automatically suggest the same phone number you entered when signing up for Duo. We recommend using a mobile phone that can receive text messages as the backup.
Use your new administrator account to log into the Duo Admin Panel. If you activated Duo Push during account setup, click the Duo Push button to receive a two-factor authentication request from Duo Mobile. If you didn't activate a smartphone for Duo Push, you can send a passcode to your phone via SMS by clicking Text Me. Enter the passcode you receive in the passcode field on the Duo login page.
Enroll your pilot users in Duo. We provide several methods for enrollment. Some applications also support self-enrollment by users when they access the protected service.
Decide which service, system, or appliance you want to protect with Duo as a test. We recommend testing with a non-production application to start. 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.
Duo will require use of TLS 1.2 and secure TLS/SSL ciphers for inbound connections as of June 30, 2023. If you are unsure how this may affect your Duo deployment plans, please see the Duo Knowledge Base article Guide to updating Duo for TLS version 1.2 and preparing for TLS 1.0 and 1.1 end of support for additional information.
