Version 2.0.3 - March 20, 2025

  • Improved accessibility with initial keyboard focus on first available authentication option and ability to traverse through all options.
  • Users can now cancel and go back to previous UI screens during offline enrollment.
  • Additional user interface fixes and improvements.

Version 2.0.2 - June 7, 2023

  • Minor log filtering improvements.
  • Resolves an issue in versions 2.0.0 and 2.0.1 which permitted users who should have been denied access to complete logon without MFA when "fail open" was set to true (Cisco Security Advisory). We recommend setting "fail open" to false and using Offline Access for macOS login to protect local authentication when the client cannot contact Duo's service.

Version 2.0.1 - March 15, 2023

  • Corrects an issue in Duo Offline Access for macOS which allowed "Mac Offline" login passcodes to be reused or replayed under certain conditions (CVE-2023-20123; Cisco Security Advisory).

Version 2.0.0 - August 25, 2022

  • Introduces offline access with Duo MFA.
  • Adds support for Mac systems featuring the Apple M1 chip.
  • Adds support for macOS 13 Ventura.
  • The minimum supported macOS version is now 10.15 Catalina.
  • Resolved an issue where smart card 2FA bypass did not enforce that the smart card’s assigned user matched the authenticating user (CVE-2022-20662; Cisco Security Advisory).
  • Resolved an issue where a time sync error upon contacting Duo's service did not respect the local fail mode configuration and always failed open.
  • Improved client logging with log-level filtering.
  • Miscellaneous user interface enhancements and fixes.

Version 1.1.1 - March 22, 2022
