Using Siri from the Lock screen of your iPhone is really convenient, but you may be better off disabling Siri access from the Lock screen of your iPhone, in order to protect your privacy and security.
Why Remove Siri From Lock Screen
Apple’s well known digital assistant, Siri, can be activated by voice from the Lock screen of your iPhone. While this is super convenient, you need to think of the possibility of someone else asking Siri for information and getting to know your personal info – Full name, Email address, Phone number and your Photo.
Or someone could post a damaging message to your Facebook account or get to know your schedule for the day by interacting with Siri.
Another reason to disable Siri access from the Lock screen is to prevent the possibility of anyone gaining access to your iMessage account using Siri.
In case you haven’t followed the iOS 9 release, a security flaw was recently exposed by YouTuber Jose Rodriquez in iOS 9 and iOS 9.0.1 that could allow someone to bypass the Lock screen (even with Touch ID enabled) and gain access to iMessage (of course with Siri’s help).
Once anyone has access to your iMessage account, it is not difficult to get to your contacts, selfies, private photos, family photos and possibly get you in trouble by sending uncomplimentary messages to your contacts.
While this particular security hole has been fixed by Apple, there is always a possibility of someone else coming up with another way to bypass Lock screen or misuse the goodness of Siri in some other way.
Disable Siri From iPhone Lock Screen
1. Tap on Settings from your Home screen.
2. Tap on Touch ID & Passcode (See image below).
3. Enter your passcode.
4. Now Switch Siri to OFF position. You will find Siri under Allow Access When Locked section (See image below).
Additional Privacy settings
In addition to disabling Siri, you may consider the following additional settings to further strengthen your privacy and security.
Enable Erase Data After Failed Passcode Attempts
1. Tap On Settings > Touch ID and Passcode
2. Toggle ON Erase Data in order to erase your phone’s data after 10 failed Passcode Attempts (See image below)
This setting will ensure that anyone trying to guess your passcode can make a maximum of 10 attempts. All the data on your iPhone will be erased when anyone exceeds 10 failed login attempts.
With this setting you need to make sure that you have a backup of your iPhone’s data on iTunes or iCloud. In case your data gets erased due to excess login attempts, you will be able to recover all your data from the backup stored on iCloud or iTunes.
Turn Off Siri Completely
In case you are pretty sure about not using Apple’s digital assistant, you may turn-off Siri completely on your iPhone by following these steps.
1. Tap on Settings > Tap on General
2. Next Tap on Siri and toggle to OFF Position
3. Once you turn off Siri you will see a pop-up (See image below)
4. Tap on Turn Off Siri to completely disable Siri from your device (See image above)
