touch-id
Germany's Chaos Computer Club announced that their biometrics team successfully bypassed Apple's TouchID biometrics login mechanism, thus showing that the fingerprint method is unsuitable for access control.
Their report states: “Biometrics is fundamentally a technology designed for oppression and control, not for securing everyday device access. [...] Forcing you to give up your (hopefully long) passcode is much harder under most jurisdictions than just casually swiping your phone over your handcuffed hands.“
