Iris scanning is a way of securely keeping the contents of your phone from prying eyes, first introduced on the Galaxy S8 and S8+. It uses the biometric information of your irises to identify you. And because virtually no two irises are alike as well as being almost impossible to replicate, scanning your irises is a fool-proof method of mobile security.
To set up iris scanning, go to Settings > Lock screen and security > Iris Scanner and enter your PIN, pattern, or password. Hold your phone up and align your eyes with the highlighted area.
Once set up, you can use iris scanning to securely access the private files and apps you have on your Secure Folder as well as use Samsung Pass to log in to your accounts quickly and safely.
Iris Scanner is available on Galaxy Note9, S9, S9+, Note8, S8, and S8+.
