In the interests of enhanced privacy, some third-party iOS apps include an option to require passcode or Face ID authentication before they can be opened, even though the iPhone is already unlocked. This puts the app’s contents behind an additional layer of security, but not all apps offer the same facility.
Until recently, Apple did not offer a way to individually lock sensitive apps like Photos, and iPhone users had to resort to Screen Time’s App Limits as a workaround. Fortunately however that’s no longer the case, because you can now create an additional security barrier for any app on your iPhone using a shortcut action new to iOS 16.4.
