In this tutorial, the process of password protecting a PDF file on iPhone is demonstrated. To lock a PDF file on your iPhone, open the Files app and ensure the PDF file is available locally. Navigate to the file, tap on the share icon, and select "lock PDF". Set and verify the desired password, then tap "done" to complete the process. It is important to note that PDF files stored on iCloud Drive cannot be locked on iOS 15. Only locally saved files can be password protected.
