Iris scan

The patterns in your irises are unique to you, meaning iris authentication is one of the safest ways to keep your phone locked and the contents private.

Easy unlocking

Life is so much easier without having to remember yet another password. That's why the Galaxy S8 and S8+ come with three easy ways to unlock your phone.

Iris Scanner

Unlock with your eyes

Hold up your Galaxy S8 or S8+ and align your eyes with the twin circles on-screen to scan your irises. This will let you unlock your phone just by looking at it.

Face Recognition

Unlock with your face

Use facial recognition by raising your phone just like you’re about to take a selfie. It's a fast and effortless way to unlock your Galaxy S8 or S8+.

*Face recognition is less secure than pattern, pin or password.

Fingerprint Scanner

Unlock with a touch

As you pick up your Galaxy S8 or S8+, your finger naturally goes to the fingerprint sensor on the back, unlocking it in one seamless movement. You don't even have to wake up the phone first.

Secure Folder

Secure your most private information

If you have files and apps that need to be kept truly private, keep them in the Secure Folder. Once there, they can only be accessed by you. Samsung's defence-grade Knox system keeps it that way. For ultimate privacy, you can also make the Secure Folder only visible to you.

Defence-grade security from the chip up

The enhanced security offered by Samsung Knox has been approved by governments worldwide. Its chip-level security reinforces several layers of protection that work at hardware and software levels. Rest assured, on the Galaxy S8 and S8+, the upgraded Knox 2.8 safeguards your data around the clock.
