Google is working on a feature that will require you to enter a PIN or submit biometric authentication before installing an APK.

TL;DR

  • Google is adding an additional layer of security when installing an APK or updating an app through an APK.
  • A PIN or biometric authentication will now be required in certain cases.
  • This will be the case for APKs that Google thinks are malicious or didn’t come from the Play Store.
