Currently, there is no national binding law regarding whether or not law enforcement or the government cannot compel you even by warrant to give up your password to them so they can access your smartphone or computer, etc. However, some courts have ruled that you must comply to grant access if the access system is Touch ID. (The preceding is why I use the password digit system for my iPhone.) Now think about the new Apple iPhone X with facial recognition. If you can legally be required to grant access via Touch ID on your phone or some other electronic device it seems only logical that facial recognition would meet the same standard.
