Android fingerprint protection isn’t that reliable after all: it can be brute-forced even without a copy of your fingerprint.
"Fingerprint recognition is believed to be a fairly secure authentication method. Publications on different ways to trick the fingerprint sensor do pop up now and again, but all the suggested methods one way or another boil down to physical imitation of the phone owner’s finger — whether using a silicone pad or conductive ink printout. This involves procuring a high-quality image of a finger — and not any finger, mind, but the one registered in the system.
In a nutshell, all these methods come with lots of real-world hassle. But is it possible to do it somehow more elegantly, without leaving the purely digital world and all its benefits? Turns out, it is: Chinese researchers Yu Chen and Yiling He recently published a study on how to brute-force almost any fingerprint-protected Android smartphone. They called the attack BrutePrint."
Do not use fingerprint protection for your crypto wallets on mobile.
