Here is the easiest way to lock iMessages on your iPhone without jailbreaking or installing any third-party apps from Apple. Just make sure that you are running an iOS version greater than 16.

To lock messages on your iPhone, start by opening the Shortcuts app. If you don’t already have it, simply download it from the app store. Next, tap on “Automation” and then the plus icon. Scroll down to find the “App” option and select the app you want to lock – in this case, we’ll choose “Messages.” Ensure you choose “Run Immediately” and turn off “Notify When Run.” Tap “Next” and create a new blank automation, adding the action “Lock Screen.”

This simple trick allows you to keep your messages protected and can be especially handy in situations where privacy is a concern. Give it a try and let us know. Thank you.
