Prevent Siri Being Used from the Lock Screen in iOS
Siri works from the Locked Screen in iOS, letting you get things like the weather, make quick phone calls, and a variety of other incredibly useful tasks, but for the privacy and security buffs out there, this may be considered undesirable.
If you don’t want Siri to be usable when the iPhone or iPad is locked with a passcode, you can disable Siri lock screen access easily, here’s how to do that.
How to Turn Off Lock Screen Access to Siri
This leaves Siri on overall but prevents access from the locked screen of an iPhone, iPad, or iPod touch, offering a sort of security measure to unintended usage of Siri.
- Open “Settings” on the iPhone or iPad, and tap to “General”
- Choose “Passcode Lock” and enter the password as usual
- Scroll down and find “Siri”, then flip Siri access to OFF
- Exit Settings as usual
The settings change is immediate, you can lock your device and test it if you’d like.
Now anytime the screen has been locked, Siri won’t be usable from the lock screen, and holding down the Home button will no longer do anything when the device is passcode protected. Of course, Siri will remain accessible once the device is unlocked and either at the home screen or within apps.
This setting is the same in all versions of iOS that support Siri, though it looks a little bit different from older pre-Ive iOS and post-Ive iOS:
For most users, the usefulness of Siri’s quick access whether the devices is locked or not will outweigh the security benefit of preventing access from a locked device. This is particularly true for those of us who always have our iPhones with us anyway, and keep in mind that for Siri to perform most tasks, a password will need to be entered anyway.
You could also go all out and disable Siri completely but that is really not recommended, it’s a great feature that has so much usage potential and helpful commands.
