Native Duo Two-Step Authentication Changes

  • Faculty & Staff
  • Students & Alumni

On Tuesday, November 14, 2023, Penn will upgrade and modernize its Duo Two-step authentication system to the Duo Universal Prompt. This will better integrate with modern two-step authentication services provided by Duo and provide enhanced services in the future.

Current PennKey Two-Step Verification users do not need to re-download the Duo Mobile app or take any actions prior to rollout, but the following changes will occur on Tuesday, November 14:

All existing “Trust this browser” sessions will expire

  • All users will need to authenticate with Two-Step upon their first login starting onTuesday, November 14.
  • Duo Universal Prompt will allow a 60-day limit on trusted browsers.

In addition, some legacy two-step functions will be retired:

  • “Generate Codes” – Replaced by code generating function within Duo Mobile app or Duo fob. Remember that the Duo app does not require cell service to produce codes.
  • User dashboard (enroll, manage settings, trouble logging in) – Replaced by Duo Universal Prompt.
  • New Google Authenticator registrations – Replaced by Duo Mobile app. (Existing Google Authenticator registrations will continue to work, but Google Authenticator users are strongly encouraged to migrate to Duo Mobile.)
  • Note that for users who use Two-step fobs – existing SafeID fobs will continue to work. Once those fobs need to be replaced (due to an expired battery), users will be able to obtain a new Duo native fob at the library.
