Know what the other person can see
Apple says a FaceTime screen-sharing participant can see most content displayed on your screen. They cannot see received notifications, and the passcode keypad is not shown normally, but apps, pages, thumbnails, and files you navigate to can be visible.
Prepare a narrow demonstration path
- Decide exactly which app and screen you need to show.
- Close Photos and other private apps before the call.
- Move the intended file into an easy-to-reach location rather than searching live.
- Check the app switcher for revealing previews.
- Open Control Center and verify which device or session is receiving the screen.
- Stop sharing before navigating elsewhere.
Review the photo library if Photos may appear
If the demonstration involves Photos, an AirPlay slideshow, or a file picker that surfaces recent media, review likely sensitive items beforehand. Apple’s Hidden album is useful for media you already know about. A library scanner can help reduce the search set, but it cannot guarantee that every private item is found.
Start a local screen recording or mirror to a trusted device and follow the exact presentation path. Look for thumbnails, recent files, search suggestions, and app-switcher previews.
Remote control is a separate permission
During a supported one-to-one FaceTime session, the other person can request remote control after you share the screen. You can decline. Apple documents additional restrictions, but a controller can still open apps, change some settings, send messages, and delete items. Allow control only to someone you trust and stop it as soon as the task is complete.
How to stop sharing
On iPhone or iPad, open the FaceTime controls, tap More, and tap Stop beside Screen Sharing. Ending the call also stops sharing. If remote control is active, use the Stop control shown in the sharing window.
