You can lock your other iPhone remotely using the Activation Lock feature. Activation Lock is a security feature that is automatically enabled when you set up Find My iPhone on your device. It prevents anyone else from using your iPhone if it’s ever lost or stolen.
To remotely lock your iPhone, you’ll need access to another Apple device with Find My iPhone enabled, or you can use iCloud.com on a computer. Here’s how you can do it:
1. On another Apple device or computer, open the Find My iPhone app or go to iCloud.com and sign in with your Apple ID and password.
2. Once signed in, you’ll see a map with the locations of your Apple devices. Select the iPhone you want to lock from the list of devices.
3. If your iPhone is online and connected to the internet, you’ll see its current location on the map. If it’s not online, the last known location will be shown.
4. Tap on the “Actions” button (represented by a dot with three lines) at the bottom of the screen or click on the “i” button next to the device name.
5. In the actions menu, you’ll find the option to “Lost Mode” or “Lock” your iPhone. Select this option.
Enabling Lost Mode will remotely lock your iPhone, preventing anyone from accessing your personal data. It will also display a custom message on the lock screen, allowing you to provide contact information if someone finds your phone. Additionally, Lost Mode will track the location of your iPhone if it’s online.
When you lock your iPhone remotely, it will display a passcode screen, and the device can only be unlocked with the passcode you set. This ensures that even if someone has physical access to your iPhone, they won’t be able to use it without your permission.
It’s important to note that you should only use Activation Lock and remotely lock your iPhone if you are sure it is lost or stolen. If you lock a device that is not lost, it may cause inconvenience for yourself or someone else who has access to the device.
In my personal experience, I once misplaced my iPhone while traveling. I immediately used Find My iPhone on my iPad to remotely lock the lost iPhone. Thankfully, a kind stranger found it and was able to contact me through the custom message I had set. This feature provided peace of mind knowing that my personal data was protected, and I could track the location of my device.
To summarize, you can lock your other iPhone remotely using the Activation Lock feature through the Find My iPhone app or iCloud.com. This ensures that your device and personal data are secure in case it’s lost or stolen.
