Upcoming DUO Changes 2024

Throughout 2024, CSUSM will be implementing several changes to increase the security of Duo due to a significant increase in phishing attacks that have targeted our university.

IMPORTANT NOTE

These changes wil require you to update your Duo app to at least version 4.49 for Android users and 4.17 for iOS users.

Duo Support for iOS

Effective February 17, 2025, Duo Mobile will no longer support iOS 15.

This end-of-support milestone means that:

  • Duo teams will no longer be able to troubleshoot issues with Duo Mobile running on iOS 15 or older.
  • Duo Push will continue to work on already-installed versions of Duo Mobile on iOS 15, and users will continue to be able to authenticate.
  • Duo Mobile–generated passcodes will also continue to work on already-installed versions of the app, and users will continue to be able to authenticate.
  • Duo Mobile will continue to be fully supported on iOS 16 or newer.
  • Mobile devices using iOS 15 will no longer receive Duo Mobile maintenance fixes or security updates.
  • Users cannot download the latest version of Duo Mobile on mobile devices running on iOS 15.

Duo Universal Prompt

Duo Universal Prompt was implemented April 1st, 2024. Universal Prompt is a new more modern look and feel to the Duo login screen. Learn more by visiting the Duo Universal Prompt webpage.

Verified Duo Push

Verified Duo Push, also implemented April 1st, 2024, is a more secure way for you to sign in by requiring you to enter a number in your Duo app. Learn more by visiting the Verified Duo Push webpage.

Duo Self-Enrollment

You can now enroll your own devices in Duo! Check out the Duo Self-Enrollment instructions.

Deprecating Telephony Authentication

In late Spring 2024, CSUSM will be deprecating the telephony authentication method. Attackers use this method to bypass the increased security offered by Verified Duo Push. You will either need to download the Duo Mobile App on your smartphone, or, you can request a Duo hardware token by contacting the CSUSM Helpdesk at helpdesk@csusm.edu.

As a reminder, NEVER share your CSUSM password, Duo Passcode, or Duo Authentication numbers with anyone. If someone asks you for any of these via email or text message consider them suspicious and do not respond; first reach out to abuse@csusm.edu. This goes for any any suspicious activity, please report and get a second opinion.
