Duo Release Notes for March 1, 2019


Hello everyone! Here are the release notes for the most recent updates we’ve made to Duo.

You can subscribe to notifications for new release notes by following the process described here. If you have any questions about these changes, please comment below.

New and updated applications

Duo Authentication Proxy version 2.14.0 released

  • The proxy now features an optional script that puts the Authentication Proxy into primary only mode, which temporarily only validates first-factor authentication and skips secondary authentication for any configuration that allows “fail open” behavior.
  • Added a support tool that sanitizes and packages config and log files into a zip file you can send to Duo Support when troubleshooting issues.
  • Improved logging during Active Directory or OpenLDAP directory synchronization.
  • Introduced support for [http_proxy] sections to use a configured interface parameter.

Duo Mobile for iOS 3.24.2 released

  • Duo Mobile now requires iOS 10 or later.
  • Minor bug fixes and improvements.

Miscellaneous updates

  • In the Duo Admin Panel applications list, SAML - Cisco Webex was renamed to SAML - Cisco Webex Meetings (with Site Admin).
  • Added SAML - Cisco Webex (with Control Hub) to the Duo Admin Panel applications list to support newer Webex Meetings and Webex Teams accounts.

New features, enhancements, and other improvements

  • Duo Administrators with the Owner role may now email themselves activation links for Duo Mobile.

Bug fixes

  • A pending-deletion user’s page is now fully read-only. Previously, 2FA devices and other elements could be edited or added to users pending deletion.
  • Single-user sync now handles users who are no longer being synced (removed from the target directory or from sync groups) in the same way as a “full” Directory Sync does:
    • Removes them from synced group(s) in Duo.
    • Sets them to pending deletion.
    • Leaves their status unchanged.


I see a notification in the Duo portal that TouchID is now working in Chrome on MacOS. However, I don’t see any details or instructions in the release notes.

Looking forward to testing this out! Thanks.



Hi David,
We publish our full public release notes here in the community once our latest software release has reached all customers. Because we use a phased deployment process, this means you may get access to features before the notes are published here.

More information on the new TouchID for authentication feature is available here: Touch ID and Beyond: Duo’s Plans for WebAuthn | Duo Security. Configuration documentation will be available soon as well.

While I appreciate the link to the blog which is very helpful. I think the confusion is coming from this message (quoted below) which appears in the Admin console and indicates that it is released March 1, 2019, but when following the included link just ends up at the general Release Notes of which the most current (also March 1, 2019) has no reference to the topic. Seems at least a bit like a cart & horse problem.

WebAuthn is now available in the Duo Prompt

Use Touch ID on MacOS with the Chrome Browser or Security Keys with Chrome or Firefox. Learn more about the WebAuthn policies and setting up a WebAuthn device in our release notes.

Appreciate the feedback! I absolutely agree that the link was unhelpful here. We’ve shared your response with our product team and are working to make sure to avoid confusing linking from that “What’s New” feed in the Admin Panel moving forward.



Hey Allen and @dg0403, much more information, including links to the new documentation, is available in the latest release notes post here: Duo Release Notes for March 15, 2019
