The upcoming iOS 18 is anticipated to introduce a new security feature that allows users to lock individual apps, according to several sources familiar with the development.

This feature is set to provide users with the ability to lock native iPhone apps such as Mail, Messages, Notes, Phone, Photos, Safari, and Settings, among others, thereby offering an additional layer of privacy and security.

To unlock a locked app, users will need to authenticate via Face ID, and it is expected that Touch ID or an iPhone’s passcode will also be compatible with this feature.

It remains unconfirmed whether this functionality will extend to third-party apps from the App Store.

Currently, Apple permits certain content to be secured behind Face ID, Touch ID, or a passcode, such as notes in the Notes app and photos in the “Recently Deleted” and “Hidden” albums within the Photos app.

The upcoming iOS 18 feature will expand this capability, allowing for entire apps to be locked, even when the iPhone itself is unlocked.

iPhone users have previously resorted to using Screen Time or Shortcuts to lock apps, but these methods will become obsolete with the new iOS 18 functionality.

Apple is set to unveil iOS 18 during its WWDC keynote on Monday. The initial iOS 18 beta is expected to be available to Apple Developer Program members immediately following the keynote, with a public release anticipated in September.
