Before you do anything on your iPhone or iPad, you should lock it down. This is how you do it.
Don't give away free access to your locked iPhone through things like Siri.
Go to Settings > Touch ID & Passcode, and enter your passcode. Scroll down to see your lock screen access. The fewer items that are on, the better. From here, you can turn off your Today view, your wallet access, and other features, like Siri and Home Control -- and now Return Missed Calls, a new feature of iOS 11.
