Apple announced its Face ID feature during the unveiling of the iPhone X in 2017, changing the face of tech at the time.
While it’s now commonplace for users to use the feature, a setting could make or break their data security.
When turned on, the Attention setting on iPhones requires a user to have their eyes open and be looking at the screen for Face ID to work.
The security feature can also reveal notifications and messages and keep the screen lit when you’re reading.
If the Attention feature is not turned on, iPhones can be opened by holding up the device to a person’s face without requiring their eyes to be trained on the device — or even open.
To turn on the feature, go to the settings app on your iPhone then click on Face ID and Passcode.
You can separately turn on Require Attention for Face ID and Attention Aware Features for features such as keeping your phone from dimming while you read.
“I have no clue why this doesn’t come on by default,” one person wrote online about the feature.
Users can also turn on Face ID with a Mask, which identifies the unique features around the eye area of the user.
This feature also requires users to be looking at their phones to work.
The Alternate Appearance feature allows users to register another way they appear, such as when wearing glasses or a head covering.
If you want to let another person unlock your iPhone using Face ID, this feature can also be used to do so.
