DUO Prompt Issues on iOS or macOS

Tags macos ios NETID

Purpose 

While logging in to a Duo-protected website or an application on any iOS or macOS devices, the Duo Prompt displays an error message saying "You cannot browse this page at 'duo.com' because it is restricted" or displays a gray box instead if the prompt. This article has the instructions to fix this error. 

Enabling JavaScript in Safari 

  • Open Safari.
  • In the top toolbar, select "Safari."
  • In the dropdown menu, click "Preferences."

  • Toggle over to the "Security" tab.

  • Check the box next to "Enable Javascript."

Disabling Content Restrictions

For iOS 12 or newer:

  • Navigate to Settings.
  • Click on Screen Time.

  • Select Content & Privacy Restrictions

  • Tap on Content Restrictions

  • Click on Web Content.

  • Uncheck Limit Adult Websites to completely disable content restrictions. 

For macOS 10.15 (Catalina) or higher:

  • Open system Preferences.
  • Click on Screen Time. 

  • Select Content & Privacy.

  • Set any Web Content restrictions to Unrestricted access. 

Note : If you do not want to fully disable content restrictions, you can allow duosecurity.com within the Content Restrictions page on the iOS device or to the Allowed Websites Only list on macOS. This will allow the Duo Prompt to display even if content restrictions are enabled.

Duo
Duo is the university two-factor authentication method designed to add a second layer of security to your NetID account. Verifying your identity using a second factor, such as your phone or a security key, prevents anyone but you from logging in, even if they know your password.
