If you want to reduce the possibility of recognising faces in photos or videos, tap the Faster recognition switch to deactivate it. This may decrease the face recognition speed.

4 On the locked screen, look at the screen.

When your face is recognised, you can unlock the screen without using any additional screen lock method. If your face is not recognised, use the preset screen lock method.

Iris recognition

The iris recognition feature uses the unique characteristics of your irises, such as their shape and pattern, to strengthen the security of your device. Your iris data can be used for various authentication purposes. After registering your irises, you can set the device to use your irises for the following features:

•Samsung Pass (Samsung account verification and web sign-in)

•Samsung Pay

•Screen lock

•Secure Folder

•This feature may not be available depending on the region or service provider.

•If you use your iris as a screen lock method, your irises cannot be used to unlock the screen for the first time after turning on the device. To use the device, you must unlock the screen using the pattern, PIN, or password you set when registering the irises. Be careful not to forget your pattern, PIN, or password.

•If your irises are not recognised, unlock the device using the pattern, PIN, or password you set when registering the irises, and then re-register your irises. If your pattern, PIN, or password is forgotten, you will not be able to use the device if you do not reset it. Samsung is not responsible for any data loss or inconvenience caused by forgotten unlock codes.

•If you change the screen lock method to Swipe or None, which are not secure, all of your biometric data will be deleted. If you want to use your biometric data in apps or features, such as Samsung Pass and Samsung Pay, you must register your biometric data again.
