Disable Siri When iPhone is Locked
For convenience, Apple allows its users to call up Siri on iPhone to check weather, play music, make a call or send a message, without the need to unlock your device. While this feature is cool and convenient, it can also be used to gain unauthorized access to your device by manipulating Siri. In general, most security experts recommend disabling any smart phone feature that by-passes the regular Lock Screen Passcode, Touch or Face ID requirements.
