Mobile Phones iPhone & iOS iPhone Lock Screen Privacy and Security Tips Keep your notifications private Share Pin Email Print iPhone & iOS Switching from Android By Andy O'Donnell Writer Andy O'Donnell, MA, is a former freelance contributor to Lifewire and a senior security engineer who is active in internet and network security. our editorial process Andy O'Donnell Updated December 11, 2019 The iPhone lock screen is a virtual billboard for app notifications, alerts, and messages. Some of this information might be personal, and you might not want someone who is standing next to you to see it. If you don't like the way the iPhone lock screen shows notifications, customize or hide the sensitive information that these notifications display. All of these tips apply to iPhone devices running iOS 10 or newer, and possibly older versions, too. Pick a Strong Lock Screen Passcode One of the most important things you can do to secure your phone while you're away from it is to implement a passcode—not just the four-digit kind. How to Strengthen Your iPhone's Passcode However, a strong password won't guard against someone looking over your shoulder or viewing your phone's lock screen. To keep your lock screen safe, manage the lock screen notifications. Disable Lock Screen Notifications Hide notifications on the lock screen so that only alerts from certain apps (or no apps) appear while your phone is locked. You control which apps show lock screen notifications. Open the Settings app and tap Notifications. Tap an app from the list for which you want to change the lock screen visibility. In the Alerts section, tap Lock Screen to disable notifications from showing up on the lock screen. Or, select Allow Notifications to disable all notifications for that app, but that will also remove banner and Notification Center pop-ups, which you might still want. If you're not using the most recent iOS version, tap the button next to Show on Lock Screen to turn it off. Repeat the process with every app in the list to either turn on or off its ability to display on the lock screen. Turn Off Siri Access From the Lock Screen Siri is handy when easily accessible, and having it there on the lock screen is usually ideal. Having Siri available there still requires security access, you might want to shut Siri off so that it can't be commanded to show anything private while your phone is locked. To disable Siri from the lock screen, go to Settings and tap Siri & Search. Scroll down and turn off the Allow Siri When Locked toggle switch. Disable Notification Center Previews on Lock Screen By default, anyone who picks up your phone can see all your notifications. You can turn off lock screen notifications while still getting them when you unlock your phone. Use the Settings app to open the Notifications section. Select Show Previews. Tap When Unlocked to make sure notification previews show up only after you unlock your phone. Or, to disable Notification Center previews when your phone is unlocked, select Never. Turn Off Message Previews Something else you can do to secure your iPhone lock screen is to keep notifications enabled but disable previews. For example, be notified when you get a text or email but turn off the message part. Anyone looking at your phone will see that you got a message but they won't know what it says. This isn't a function of every iPhone app but some include it as an option. What makes this different than the notification preview settings above is that the app controls the alerts, not the phone settings. For example, as shown in this screenshot, the Signal app includes an option to show only the name of the person texting you, or you can show no name or message but include an alert that someone messaged you. Change the Lock Screen Wallpaper When you don't want anyone to find out about you by looking at your iPhone lock screen, remove personal information from the lock screen, such as a wallpaper that shows your face or a family photo. Changing your iPhone wallpaper is easy. Just choose something not so identifying.
