1. iOS 18 Might Allow Users to Lock Built-in iPhone Apps Using Face ID
- According to reports, the upcoming iOS 18 update may introduce a new feature that allows users to lock specific built-in iPhone apps using Face ID.
- This feature would provide an additional layer of security for sensitive apps, such as Wallet, Health, and Podcasts, by requiring Face ID authentication to access them.
- The ability to lock apps with Face ID could be particularly useful for users who share their devices with others or want to ensure the privacy of certain app data.

2. Improved App Privacy and Security
- The potential Face ID locking feature in iOS 18 is part of Apple's ongoing efforts to enhance app privacy and security on the iPhone.
- By allowing users to secure specific apps, this feature could help prevent unauthorized access to sensitive information and prevent accidental or intentional misuse of certain apps.
- This addition would further strengthen the iPhone's overall security ecosystem and give users more control over the privacy of their data.

3. Potential Availability and Compatibility
- The reports suggest that the Face ID locking feature for built-in iPhone apps may be introduced with the release of iOS 18, which is expected to be unveiled later this year.
- However, it's important to note that the feature is still in the rumor stage, and Apple has not officially confirmed its inclusion in the upcoming iOS update.
- If the feature is indeed implemented, it's likely that it will be compatible with all iPhone models that support Face ID, which includes the iPhone X and later.
