Why does a password offer better protection than fingerprint, face recognition or iris scanner security?

While the technology behind biometrics improves on a regular basis, it still has some limitations. If someone wanted to unlock your phone, they could scan your finger/thumb while you’re sleeping as it happened here . Furthermore, they could use your picture or place the phone in front of you sleeping to unlock using facial recognition. Moreover, some courts have ruled that you can be forced to unlock you phone if you used a fingerprint or facial recognition to lock your phone. However, you are able to remain silent about your passwords as to limit someone’s ability to unlock it.
