Troubleshooting 2-Step on iOS (iPhone/iPad)
Issue: Content restrictions or parental controls on mobile devices can interfere with the verification panel and prevent the login screen from loading properly.
If you encounter a blank screen or loading error, please disable parental controls or content restrictions on your device and try again.
For specific instructions on checking content restrictions on an iOS device, see the Duo Support website.
Recommended Troubleshooting Steps
If the 2-Step panel still fails to load on Safari, check the following settings on your iOS device:
- Ensure JavaScript is enabled in your Safari settings.
- Check that there is no ad-blocker enabled in Safari.
- Verify there is no unfamiliar Configuration Profile, MDM, or VPN installed.
- Ensure Screen Time restrictions are turned off.
- Verify that Focus Mode is disabled.
- Once restrictions are disabled, clear your browser cache.
