An owner password is a special password you set when you apply restrictions to a PDF. It is different from a password to open the document.

The 'Changes Allowed' option specifically governs actions like inserting, deleting, rotating pages, or extracting content. Filling out form fields is a separate action and is usually permitted even with editing restrictions.
Defining access controls is crucial for protecting sensitive information and maintaining document integrity. It ensures that only authorized actions, like viewing or printing, are allowed. This prevents unauthorized editing, copying, or distribution, which can protect intellectual property, comply with regulations, and prevent data leaks. It gives you control over how your document is used after you share it.
