Is it possible to wipe Samsung S5 finger print scanner data from recovery I heard Samsung S5 has finger print scanner to unlock screen. How reliable is this? If I perform a data wipe or factory reset via recovery will the finger print lock still works?
The purpose of the lockscreen is to prevent someone from accessing your data, which would be erased by performing a factory reset. A fingerprint scanner is not more secure than a password, it's only more convenient. A few cases where it falls short as a password are:


You leave your fingerprints everywhere
Its easier to obtain your fingerprints by force, than a password
Its harder to change your fingerprints than a password
