I was wondering if the Android fingerprint login had been compromised since the days of the gummybear attacks. For anyone else who was wondering: https://www.bleepingcomputer.com/news/security/android-phones-are-vulnerable-to-fingerprint-brute-force-attacks/
Interesting question OP, I’ll be (academically) interested in the answer.
