Fingerprint ID Systems More Vulnerable than Once Thought
By FF Newsroom · 12 April 2017

University researchers have recently proved that "partial similarities between prints are common enough that the fingerprint-based security systems used in mobile phones and other electronic devices can be more vulnerable than previously thought" - Help Net Security.
Commenting below is Niel Bester, SVP Products, Entersekt:
“Biometrics does not present a silver bullet, even though it brings with it significant convenience. If a person’s PIN or password is stolen, it can always be updated – but a compromised biometric factor like a fingerprint is much harder to revoke, and cannot necessarily be replaced. So, while biometric data helps identify the user, a second factor of authentication must be in place to verify that identity – and, in the case of digital banking, the user’s intention to carry out a specific transaction.”
