As business applications move from on-premises to cloud hosted solutions, users experience password fatigue due to disparate logons for different applications. Single sign-on (SSO) technologies seek to unify identities across systems and reduce the number of different credentials a user has to remember or input to gain access to resources.

While SSO is convenient for users, it presents new security challenges. If a user's primary password is compromised, attackers may be able to gain access to multiple resources. In addition, as sensitive information makes its way to cloud-hosted services it is even more important to secure access by implementing two-factor authentication.

About Duo Single Sign-On

Duo Single Sign-On is our cloud-hosted SSO product which layers Duo's strong authentication and flexible policy engine on top of ShareFile logins using the Security Assertion Markup Language (SAML) 2.0 authentication standard. Duo Single Sign-On acts as an identity provider (IdP), authenticating your users using existing on-premises Active Directory (AD) or any SAML 2.0 IdP and prompting for two-factor authentication before permitting access to ShareFile.

Duo Single Sign-On is available in Duo Beyond, Duo Access, and Duo MFA plans, which also include the ability to define policies that enforce unique controls for each individual SSO application. For example, you can require that Salesforce users complete two-factor authentication at every login, but only once every seven days when accessing ShareFile. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Configure Single Sign-On

Before configuring ShareFile you'll first need to enable Duo Single Sign-On for your Duo account and configure a working authentication source.

Once you have your SSO authentication source working, continue to the next step of creating the ShareFile application in Duo.

Create the ShareFile Application in Duo

  1. Log on to the Duo Admin Panel and navigate to Applications.

  2. Click Protect an Application and locate the entry for ShareFile with a protection type of "2FA with SSO hosted by Duo (Single Sign-On)" in the applications list. Click Protect to the far-right to start configuring ShareFile. See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the ShareFile page under Metadata later.

  3. The ShareFile Subdomain is the subdomain used when logging into your company's ShareFile site. For example, if your ShareFile login URL is, enter example.

  4. ShareFile uses the Mail attribute when authenticating. We've mapped the bridge attribute to Duo Single Sign-On supported authentication source attributes as follows:

    Bridge Attribute Active Directory SAML IdP
    <Email Address> mail Email

    If you are using non-standard attributes for your authentication source, check the Custom attributes box and enter the name of the attributes you wish to use instead.

  5. You can adjust additional settings for your new SAML application at this time — like changing the application's name from the default value, enabling self-service, or assigning a group policy.

  6. Scroll to the bottom of the page and click the Save button. Leave this page open as you'll need information from it later.

Duo Universal Prompt

Duo's next-generation authentication experience, the Universal Prompt, is coming to web-based applications that display the current Duo Prompt in browsers.

Migration to Universal Prompt for your ShareFile application is a two-step process:

  • Duo updates the ShareFile application to support the Universal Prompt.
  • You activate the Universal Prompt experience for users of that Duo ShareFile application (when the Universal Prompt becomes available).

We've already updated the Duo ShareFile application hosted in Duo's service to support the Universal Prompt when it's ready, so there's no action required on your part to update the application. The "Universal Prompt" section of this application's details page in the Admin Panel reflects this status today as "Waiting on Duo".

Activate Universal Prompt

When the Universal Prompt becomes available, you'll return here to activate it for users of this application. The status will change to "New Prompt Ready", and you'll see the control here for turning it on or off. Until then, your users continue to experience the current Duo prompt.
