Duo's next-generation authentication experience, the Universal Prompt, provides a simplified and accessible Duo login experience for web-based applications, offering a redesigned visual interface with security and usability enhancements.
Duo Universal Prompt is generally available for in-scope applications that display the Duo traditional prompt today in browsers and select thick-client applications that use single sign-on. See which of your Duo applications can migrate to the Universal Prompt at a glance from the Universal Prompt Update Progress report
|Universal Prompt||Traditional Prompt|
Future updates to the Universal Prompt will extend the new experience to endpoint remediation and management verification functionality.
Your complete migration from traditional Duo prompt to Universal Prompt for a given application will be a two-step process:
Update the application to support the Universal Prompt. This may involve installing a software upgrade provided by Duo or one of our technology partners on your application server, or making a configuration change in the admin console of a cloud-hosted application where you use Duo.
Duo and our partners are working to make more application updates available.
In the Duo Admin Panel, enable the Universal Prompt experience for users of that application after the application has been updated with Universal Prompt support.
Watch the Duo Blog for future updates about the Duo Universal Prompt.
The Universal Prompt does not yet have full feature parity with the traditional prompt.

Enhanced localization and language support. The end-user's browser language settings determine the language shown in the prompt and used for Duo Mobile activation, and SMS passcode text messages. No extra language configuration steps are necessary for Duo administrators or users. Administrators may also configure translated custom help desk messages in User Communication settings. The "Language" setting selected in the Admin Panel has no effect on the language shown in the Universal Prompt.
English, Spanish, French, German, and Japanese: When these languages are used in the Universal Prompt, phone callback authentication will also use the same language.
Chinese (Simplified), Czech, Danish, Finnish, Hindi, Indonesian, Italian, Korean, Norwegian, Polish, Portuguese (Brazil), Swedish, Thai, Turkish, and Vietnamese: When these languages are used in the Universal Prompt, phone callback authentication remains in English.
Expanded custom branding which permits customization of the Universal Prompt background image and color bar in addition to the existing customization settings for company logo and hiding the Duo branding line.
Features and functionality in active development:
We'll let you know when the Universal Prompt experience includes these features.
The Universal Prompt supports Chrome (Desktop and Mobile), Firefox, Safari (Desktop and Mobile), Edge, and Internet Explorer. Not all browsers support all Duo authentication methods, so for the widest compatibility we recommend Chrome.
Check the table below for supported browser versions and Duo login option compatibility. Duo's support for the minimum browser version includes Duo Push, passcode, and phone call authentication options. Other login options, like Touch ID, may require a different browser or a newer minimum browser version, as noted in the table.
|Safari||9||13 on macOS
13.4 on iOS
|Internet Explorer||11||Not supported||Not supported|
While other browsers may work with the Universal Prompt, we actively test and support the browsers and minimum versions listed in the table.
When you log in Duo checks your current browser or client compatibility with the Universal Prompt. If your browser or client is not compatible, Duo will show you the traditional prompt experience instead.
We've made some underlying changes to support the Universal Prompt user experience.
Duo delivers the traditional prompt via an inline frame (or "iFrame") using our v2 WebSDK, which means that the Duo Prompt web content is embedded within a web page hosted by the protected application.
Duo Traditional Prompt in an iFrame
When planning for the Universal Prompt it soon became apparent that switching from use of inline frames to a "frameless" approach, derived from OIDC standards, would provide enhanced stability and compatibility across our web application integrations, and lay a foundation for future improvements to Duo authentication and device trust.
The most obvious difference between traditional iFrame Duo 2FA applications and updated frameless Duo 2FA applications is that instead of showing the Duo Prompt within a page hosted by the application, the application will instead redirect to a page hosted by Duo at
duosecurity.com to show the Duo Prompt, and then redirect back to the protected application after the user completes two-factor authentication. The redirect page shows either the Universal Prompt or the traditional prompt; dependent on the Universal Prompt activation status for that application.
Duo Universal Prompt in a Redirect
Duo Traditional Prompt in a Redirect
To achieve the "iFrame to frameless" migration, we've updated the Duo Web SDK with this new technical design as version 4.0, and have begun using this updated v4 SDK to bring the Universal Prompt to Duo's own web application integrations such as 2FA for Confluence, Duo Single Sign-On apps, and Duo Network Gateway, to name just a few.
Customers and technical partners should make use of the Duo Web v4 SDK and OIDC standards-based API today to begin the process of updating developed Duo integrations to support the Universal Prompt.
Each Duo application you create has a unique identifier and an associated key used to sign or verify the two-factor authentication request. These are called the "Integration Key" or
ikey and the "Secret key" or
We've relabeled these two pieces of application information to better align with the OAuth 2.0 specification. These values are now known as the "Client ID" or
client_id and the "Client secret" or
client_secret for applications that support Universal Prompt.
The names may have changed, but the values for any existing integrations remain the same.
Beyond the visual refresh of Duo's login prompt, the Universal Prompt makes some key changes to how users complete two-factor authentication.
Refer to the Universal Prompt End User Guide to learn more about the login experience for users.
The first time a user accesses the Universal Prompt for a given application, Duo evaluates the supported authentication methods for that type of application and the effective authentication methods policy for that application, and then automatically selects the most secure authentication option available to the user according to this ordered preference:
Duo authentication methods from most to least secure:
If a user wants to try a different method then the one selected for them, clicking Other options in the Universal Prompt shows a list of the user's available authentication methods, subject to the effective authentication methods policy for that application.
When a user successfully logs in to a Duo-protected application, the Universal Prompt remembers the authentication method used and defaults to that method for future logins to that application. If a user wants to try a different method then the one used last, clicking Other options in the Universal Prompt shows a list of the user's available authentication methods, subject to the effective authentication methods policy for that application.
The traditional prompt does not remember the last used device, showing all available authentication methods for the user.
If Duo Push authentication is explicitly selected by a user, or automatically selected on behalf of the user during a first-time authentication, then Duo sends the push notification to the user's activated device. If you've enabled Duo Push verification then the Universal prompt displays the code for the user to enter while approving the Duo Push request.
During future authentications by that user to that application, Duo Push continues to send the push to the user automatically. There is no way for users or administrators to disable automatic Duo Push in the Universal Prompt.
In the traditional prompt a user clicks the Send Me a Push button upon landing on the prompt, or the user may have opted to configure Duo Push as an automatic authentication option when they enrolled that device.
The Universal Prompt's list of authentication options (shown when a user clicks "Other options" in the prompt) separates out different methods for a single device into individual selections, and shows the available options for all devices in a single list, with the more secure authenticator options listed first (i.e. fingerprint sensor ahead of phone call, etc.).
If the application or group policy prevents use of any authentication methods, the authentication options list shows only those methods permitted for use by the effective policy i.e. if the effective policy disallows phone call and SMS passcodes then the options shown by Universal Prompt would not include "Call phone" and "Send text message passcode".
The traditional prompt displays the available authentication methods for a single device at a time. If a user has more than one device enrolled (i.e. two phones activated for Duo Push, or a phone and Touch ID), the user would first need to use the device selector to choose from their enrolled devices, and then make the second choice of which authentication method to use with the selected device.
If a user clicks the text message passcode option in the list then the Universal Prompt immediately generates and sends an SMS message with a single passcode, regardless of what you have configured in the SMS batch size setting.
If your users need to authenticate in the Universal Prompt when they do not have cell or data service available for their phones, we recommend they activate Duo Mobile on their phone and use it to generate a passcode while offline, or to use a hardware token or security key.
If a remembered devices policy is in effect for an application, Universal Prompt shows the initial browser trust option to the user after they complete two-factor application approval. The user chooses whether to trust the browser or not, and then continues to the application.
Opting to trust the browser sets a cookie which allows bypassing two-factor authentication from that browser for as long as the trusted session cookie remains valid. Depending on how you configured your remembered devices policy, the user may bypass two-factor authentication for that one application, or multiple applications.
When the remembered device cookie expires, the Duo two-factor authentication prompt for that application shows "Trust browser" as an enabled option on the Duo Push, phone call, text message, and passcode authentication screens. Users can uncheck the box before completing Duo authentication to log in without trusting the browser, or leave it enabled to set a new remembered device cookie for the application.
When using a WebAuthn method like Touch ID or a security key after the remembered device cookie expires, users who want to log in without creating a new remembered device session need to cancel the authentication in process to see the "Trust browser" option, and then try the authentication again after unchecking the box.
If the application has no remembered device policy applied the Universal Prompt does not show the browser trust screen, and proceeds directly to the application after 2FA success.
The traditional prompt shows the "Remember me..." option in the two-factor prompt before the user completes authentication, and does not show the option if the application has no remembered devices policy.
If users with combination U2F/WebAuthn security keys did not previously update their U2F key enrollment to WebAuthn in Duo's traditional prompt, those security keys will not be offered as authentication options by the Universal Prompt. These users will be able to enroll the U2F security key as a new WebAuthn security key in the Universal Prompt.
As mentioned, Duo's Universal Prompt supports applications that show the traditional Duo Prompt and device management as a web page today, but with some exceptions.
As Universal Prompt support becomes available for these in-scope applications, you'll find links to the application update instructions here. Update instructions are also linked from the Universal Prompt section of an eligible application's page in the Duo Admin Panel.
Duo-owned applications are delivered as setup packages downloaded from duosecurity.com for installation on your on-premises applications, or are built into cloud applications hosted by Duo.

Duo Authentication for AD FS 2.x. Duo's MFA adapter for AD FS 3.0 and later (supporting Windows Server 2012 R2 and later server releases) has the necessary updates for Universal Prompt, but there are no further feature updates planned for the AD FS 2.0 (Windows Server 2008 and 2008 R2) and AD FS 2.1 (Windows Server 2012) IIS-based Duo two-factor solution.
We encourage you to migrate to a more recent version of Windows Server and AD FS that permits use of the Duo AD FS multifactor plugin v2.0.0 or later plugin which provides Universal Prompt support.
Any Duo application with an End of Life or End of Support notification on its documentation, i.e. Duo for Drupal 6 and 7.
We'll continue to show and support the iFrame-based Duo Prompt for these applications as we explore alternate configurations that provide a path forward, such as migrating from RADIUS authentication to Duo Single Sign-On SAML implementations.
Duo Applications that do not show the browser-based Duo Prompt today are neither in-scope for Universal Prompt support nor affected by the planned iFrame and traditional Duo Prompt end of life (list not exhaustive):
As Duo adds support for the Universal Prompt to applications, you'll see a new section on the details page of the application indicating your progress toward the Universal Prompt for that application, and that application's update status appears on the Universal Prompt Update Progress report.
Most on-premises applications will require that you install a software update with the necessary changes to support the Universal Prompt on your web application server. This software update may be supplied by Duo or by our technical partners, depending on who developed the integration. Users of cloud-hosted SaaS services may need to make a configuration change to your account to enable the Universal Prompt support, at the direction of Duo or the Duo partner that operates the service.
Once an application update becomes available and you've applied it, you then need to authenticate at least once using the updated application so that Duo makes the Universal Prompt activation settings available for that application.
After Universal Prompt becomes generally available, we'll continue providing updates so that more Duo-developed integrations can offer the new prompt experience, and will support customers and technology partners who have developed WebSDK v2 integrations with their update efforts.
The status shows "Waiting on App Provider" when viewing the Universal Prompt information for an application created by one of Duo's technical partners that has no update available. Contact the application provider to request Duo Universal Prompt support.
Your users continue to see the current Duo prompt experience until an application update becomes available, you apply the update and authenticate using the updated application, and you then activate the Universal Prompt.
Application waiting on update availability
Applications maintained by Duo show the "Waiting on Duo" status when viewing the Universal Prompt information for an application that has no update available. Contact Duo Support to request Duo Universal Prompt support.
Your users continue to see the current Duo prompt experience until Duo makes an application update available, you apply the update and authenticate using the updated application, and you then activate the Universal Prompt.
Duo-owned application waiting on update availability
When Universal Prompt support becomes available for a given Duo integration, whether maintained by Duo or by a partner (or by you, our customer, for any Duo applications you may have developed in-house), the Universal Prompt details on that application's properties page in the Duo Admin Panel indicates availability of an application software update as "App Update Ready" with a link to update instructions.
Your users continue to see the current Duo prompt experience until you apply the update and authenticate using the updated application, and then activate Universal Prompt for that application.
If you see this status for a Duo WebSDK application you developed in-house, you will need to update your application from Web SDK v2 to Web SDK v4 before you can use the Universal Prompt. If you did not develop the application, please contact the software vendor that did to determine availability of the necessary update.
Application update available
Once you apply the necessary updates to an application and authenticate to Duo with the update in place, the Universal Prompt details show that the application is ready for the new prompt experience. The status "New Prompt Ready" for updated applications reflects that you've done all the work required to update your application for the Universal Prompt.
Duo hosts two applications within our cloud service which we've already updated with Universal Prompt support: Microsoft Azure Active Directory and Duo Single Sign-on (SSO). You can enable the new prompt right away for the Microsoft Azure application or for SSO service provider applications that use Duo Single Sign-On, including Duo Central.
Use the activation control options to determine the login experience for your users:
Show traditional prompt: Your users experience Duo's traditional prompt when logging in to this application.
Show new Universal Prompt: Your users experience the Universal Prompt when logging in to this application. Default selection for newly-created supported applications.
Your users continue to see the current Duo prompt experience until you activate the Universal Prompt.
Application ready for Universal Prompt
Activation of the Universal Prompt is a per-application change. Activating it for one application does not change the login experience for your other Duo applications.
Enable the Universal Prompt experience for an application by selecting Show new Universal Prompt in the activation options, and then scrolling to the bottom of the page to click Save.
Once you activate the Universal Prompt, the application's Universal Prompt status shows "Update Complete" here and on the Universal Prompt Update Progress report.
