iOS 11 Allows Users to Disable Touch ID
A new feature in Apple’s new iPhone operating system—iOS 11—will allow users to quickly disable Touch ID.
A new setting, designed to automate emergency services calls, lets iPhone users tap the power button quickly five times to call 911. This doesn’t automatically dial the emergency services by default, but it brings up the option to and also temporarily disables Touch ID until you enter a passcode.
This is useful in situations where the police cannot compel you to divulge your password, but can compel you to press your finger on the reader.
