DUO Prompt Issues on iOS or macOS

Tags macos ios NETID


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.
