Our Supreme Court has recently decided that police will require a search warrant to search a cell phone that is password protected, since a password indicates the user expects privacy. In this one case in Virginia the Judge decided that a fingerprint lock is a username and not a password. To my knowledge this has not yet been a legal issue in Canada but now no doubt will be soon. As this writer recommends: “don’t use your fingerprint to unlock it and turn on the option to erase the data on your phone after 10 failed unlock attempts.”
