Unless your the lock screen is locked, anyone who picks up your iPhone can read your notifications. If you want to hide your private WhatsApp conversations from your lock screen, you can turn off notification previews in two different ways.
Turn off notification previews on your lock screen
One of the new features introduced with Face ID on iPhone X was the ability to hide preview notifications. The feature was deployed in iOS 11 and is available for all iPhones, including older iPhones with Touch ID.
The option is enabled by default for devices with a Face ID sensor (one of the best IPhone privacy features), but you can activate it manually if you have an older iPhone.
When enabled, the content of all notifications is hidden by default. The notification will display the name of the sender and the text of the notification will simply say “Notification”.
When you unlock your iPhone with Face ID, the notification expands to display the content.
If you have disabled the feature or are using an older iPhone, you can enable it from the settings.
Open the “Settings” application then press the “Notifications” option.
Here, tap on the “Show previews” option at the top.
Go to the “Once unlocked” option. From now on, your iPhone will only develop the content of the notification after having scanned your face using Face ID or after placing your finger on the Touch ID sensor.
If you want to be extremely careful and don’t want the content of notifications to appear on the lock screen, choose the “Never” option.
Disable WhatsApp notification previews
The previous method is an all or nothing agreement for each notification that arrives on your iPhone. But what if you only want to turn off notification previews for WhatsApp and not for other apps? You can do this using a setting in the WhatsApp app.
Open the “WhatsApp” application and press the “Settings” tab located in the lower right corner.
From there, choose the “Notifications” option.
Here, tap the toggle next to the “Show preview” option.
Now when you receive a new message on WhatsApp, the notification will tell you the name of the sender and the content area will just read “Message”.
This is just one of the many steps you can take to make your WhatsApp account more secure and private. Take a look at our WhatsApp security guide to learn more.
