>In addition, there are additional restrictions where your passcode will be required. For example, if the passcode has not been used to unlock the device in the last six days and Face ID has not unlocked the device in the last eight hours, then you must use a passcode to access the device (in other words, biometric unlock is automatically disabled).

The conditions for triggering this is so unreliable that it probably exists more to prevent people from forgetting their pins, than meaningfully increase security.
