Ruling: Thumbprint scan is like a "blood draw or fingerprint taken at booking."
The legal situation is more complex and nuanced than the headline implies, so the article is worth reading. This adds another ruling to the confusing case history regarding forced biometric unlocking.
I looked into it a few years ago. Eg left thumb locks biometrics and requires pw (thus saving you from this particular law) . Right thumb just unlocks like normal.
Back then it was impossible, because biometrics couldn't differentiate between fingerprints for lord knows which security reason.
No idea if there is a solution for this already, but imo it would be a very important security feature.

For convenience, I use biometrics to unlock a few apps. But I haven't found a way to do that and be able to use only pin to unlock the phone (android) @TaviRider
