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 such as Screen lock, Web sign-in,
Verify Samsung account, Secure Folder, Samsung Pay (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 when turning on the device. To use the device, you must unlock
 the screen using a 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 recognized, 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.
