Features like “Switch Control” or “Voice Control” can be configured to trigger actions, including simulated button presses or gestures that could initiate a lock. However, these are more complex to set up and are generally intended for users with specific accessibility needs.
Siri Commands for Device Actions
While Siri doesn’t have a direct “lock my iPhone” command that works consistently when the phone is locked, it can perform other actions that indirectly contribute to security. For instance, if you’re using your iPhone and want to lock it without swiping, you can ask Siri to “Turn on Do Not Disturb” or “Turn off Bluetooth” (if you’re relying on Bluetooth proximity for another device). The most direct Siri action for locking would typically be through controlling another device, such as asking Siri on an Apple Watch to lock your iPhone.
Back Tap Gesture (Indirect Hands-Free)
A clever way to achieve a similar result without physically touching the screen is by using the “Back Tap” feature on newer iPhones. You can configure a double or triple tap on the back of your iPhone to perform an action.
To set up Back Tap for locking:
- Go to Settings.
- Tap Accessibility.
- Tap Touch.
- Scroll down to “Back Tap.”
- Choose either “Double Tap” or “Triple Tap.”
