To comply with UC-wide policy to protect UC ANR and its employees' data, IT is taking steps to strengthen security for logins. The following changes to the Duo authentication process will go into effect on Jan. 13, 2025. 

Please ensure you are using:
Duo Mobile 4.16.0 or later on Android devices
Duo Mobile 4.17.0 or later on Apple devices

How to update

• Open the app store on your device (Google Play Store for Android or Apple App Store for iOS).
• Search for "Duo Mobile" and select the app.
• Tap "Update" to install the latest version. (If the "Update" option is not there, you are already updated.)

What's changing

IT will be enabling Duo's Verified Push for UCANRSSOlogins. When youlogin using UCANRSSO (Fig. 1), Verified Push will require that you enter a code into the Duo Mobile app.

After your device is verified, you can choose "Yes, this is my device" (Fig. 4) to stay verified for 16 hours. During this time, Duo won't ask you to verify again as long as you're using the same browser.
