1. Rumor: iOS 18 to Feature Per-App Face ID Locking
- According to a rumor, Apple is reportedly considering introducing a new feature in iOS 18 that would allow users to lock individual apps with Face ID.
- This feature would provide an additional layer of security for sensitive apps, ensuring that only the device owner can access them using their biometric authentication.
- The implementation of this feature could potentially involve a settings menu where users can choose which apps they want to secure with Face ID.

2. Potential Benefits and Use Cases
- The per-app Face ID locking feature could be particularly useful for apps that contain sensitive information, such as banking, health, or personal finance apps.
- It would give users more control over the security of their data and provide an extra layer of protection against unauthorized access to specific applications.
- This feature could also be beneficial for families or shared devices, allowing users to selectively lock certain apps to prevent others from accessing them.

3. Possible Challenges and Considerations
- The implementation of this feature may raise some concerns about the user experience, as it could potentially add an extra step for users to access their apps.
- Apple would need to carefully design the feature to ensure that it is intuitive and does not significantly impact the overall app usage experience.
- Additionally, the company may need to address any potential technical or security-related challenges that could arise from implementing per-app Face ID locking.
