While Samsung didn't introduce major hardware changes with the Galaxy Z Fold 6, it still improved the phone's user experience through minor changes and optimizations. One such improvement has been made to how a new fingerprint can be added.
Galaxy Z Fold 6 fingerprint registration process has improved
Earlier Galaxy Z Fold phones required you to unfold the device to register a new fingerprint. However, that limitation has now been removed. With the Galaxy Z Fold 6, you can register a new fingerprint while keeping the phone unfolded and using the cover screen. This change was spotted by 9To5Google, and it is a welcome change.
It still isn't clear if this feature will be limited to the Galaxy Z Fold 6 or released to previous compatible Galaxy Z Fold phones with the One UI 6.1.1 update. In our understanding, nothing should stop Samsung from bringing this feature to previous-generation Galaxy Z Fold phones, as they all use a side-mounted fingerprint reader from Goodix.
There appears to be a bug in the phone's current firmware version that prevents users (via 9To5Google) from registering their fingerprints while setting up the phone for the first time.

While some Chinese brands have started offering under-display fingerprint readers in their new foldable phones, Samsung is sticking with a side-mounted capacitive fingerprint reader for its foldable phones. And that is perfectly fine. The side-mounted fingerprint reader on Galaxy Z Flip and Galaxy Z Fold phones is accurate, fast, and reliable, and it can be accessed when the phone is folded or unfolded.
Apart from fingerprints, Samsung offers alphanumeric, pattern, and PIN-based user authentication systems on its phones. They can be used to unlock the phone, unlock sensitive apps like banking, and secure features like Secure Folder.
