You should be more worried about your local doctor's office contracting some cheap-ass company to handle your data and ending up in a branch than being concerned about biometrics.

Or hell, Experian had that insane breach of basically everyone's information years ago. Biometrics are not the problem, it's smaller companies that you have to deal with all the time skimping on security because they think they can't afford it.

And then companies even more shady than Google and Apple and Samsung (loan companies, health systems contractors, banks, credit card companies, insurance companies) have all your data and are more likely to be involved in a data breach.

Using biometric data to unlock your phone does not make you more vulnerable to petty criminals.
