Which feature enhances the security of data stored on iOS devices?

The Find My device function significantly enhances the security of data stored on iOS devices by providing users with a robust set of tools to locate and protect their devices. When enabled, this feature allows you to track your device's location, which is particularly useful if it’s lost or stolen. It also enables you to remotely lock the device or erase its data, ensuring that personal information does not fall into the wrong hands.

This capability creates a safeguard around sensitive information stored on the device, minimizing the risk of unauthorized access. Additionally, if someone tries to disable the Find My device function or erase the device, they would need to authenticate with the user's Apple ID and password, adding another layer of protection.

While other features mentioned may have their benefits, such as enhancing usability (like accessibility features or automatic screen brightness) or facilitating file sharing (like AirDrop), they do not focus specifically on securing data in the same direct manner that Find My device does.
