This article will walk you through the various ways of disabling the iOS personal assistant, Siri. This will allow you to disable the application completely, turn off Siri Suggestions, and/or remove her from your lock screen features.

Siri is automatically activated if you’ve set up your iOS device using the default settings. You can launch Siri using the “Hey Siri” command or by holding down the Home button for a few seconds (this also works when the device is locked). Go to Settings > General > Siri. The Siri menu will give you access parameters and settings for the intelligent assistant, such as Voice Gender, Language, Voice Feedback and Allow “Hey Siri”.

Simply toggle the Siri switch to deactivate or reactivate any of these features. If you'd like to learn how to turn off Siri Suggestions please read our tip here. It has been reported on several technology websites that there’s a Siri exploit to bypass Touch ID and Passcode of iOS9. Removing Siri from the lock screen features can help to mitigate the risk of being hacked.

Go to Settings > Touch ID & Passcode > Allow access when locked. Then toggle Siri off.
