This is just flat-out wrong. Police can absolutely compel you to use your fingerprint on the device if they have a warrant which is exactly what happened in the Face ID context in that article. Any type of biometric identification can be compelled via warrant. Passcodes, on the other hand, cannot because that would violate the search and seizure clause of the Constitution. And, in either case, that doesn't really matter as Face ID/Touch ID can both be disabled by tapping the power button on every iPhone. In terms of security for that specific case, they're both equally secure. Face ID, however, has a much lower rate of false positives than Touch ID (with the notable exception being twins).
