Notably, Samsung has integrated its fingerprint scanner throughout the operating system.
You can register a total of 8 fingerprints and assign each fingerprint a different task or use it as an app shortcut, but at least 1 fingerprint must be used to unlock the device. A new Personal Folder and Private Mode has been developed by Samsung, where you will be able to hide personal apps, widgets, and content you want to keep private. To open and close your Personal Folder and Private Mode, you would need to swipe your registered finger over the home key after tapping on the home key, or you could simply use a different security method, like pattern unlock or security PIN. You will be able to verify your Samsung account using your fingerprint and will also be able to sign into different websites, without needing to enter your username or password ever again.
SamMobile also notes that as you are swiping your finger across the Home key, the Galaxy S5 shows a real-time image of your fingerprint as it's being scanned.
Fingerprint sensors that require a swipe are generally considered less accurate; however, the site says that other smartphone manufacturers such as Apple and HTC are not making full use of the technology; whereas, Samsung is aiming to use the sensor to its full potential.
