What’s interesting is that the DC Circuit doesn’t allow authorities to force someone to unlock their device with biometrics. I’m assuming that Natanson’s home is not inside the DC Circuit.

It’s a legally unclear area right now whether or not authorities can force you to unlock your device with biometrics. As such, it’s better not to use them: https://decentproject.org/should-you-use-biometrics-on-your-phone
