Iris scan

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

Three hassle-free ways to unlock your phone

Life is so much easier and simpler without the trouble of having to remember one more password, one more PIN. And that's why the Galaxy S8 and S8+ come with three easy ways to unlock your phone.

Iris Scanner

Open with your eyes

Hold up your Galaxy S8 or S8+ and align your eyes with the twin circles on-screen to scan your irises. Your phone is unlocked with a look.

Face Recognition

Open with your face

Raise your phone as if taking a selfie to use face recognition. 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

Open with a touch

As you pick up your Galaxy S8 or S8+, your finger goes naturally to the fingerprint sensor on the back and it's unlocked in one seamless move. You don't even have to wake the phone up 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. And Samsung's defense-grade Knox system keeps it that way. For ultimate privacy, you also have the option to make the Secure Folder visible to only yourself.

Secure Folder for enhanced privacy

Defense-grade security from the chip up

The enhanced security offered by Samsung Knox has been approved by 29 governments worldwide. Its chip-level security reinforces several layers of protection that work at hardware and software levels. On the Galaxy S8 and S8+, the upgraded Knox 2.8 is in position to safeguard your data around the clock.
