About This Feature

Overview

Document Encryption helps protect document content and currently supports password-based protection. On iOS, you can set an open password and a modify password for a document to control viewing and editing access.

Core capabilities include:

  • Set password protection for a new or existing document to add access control.
  • Manage existing encryption settings by turning off the open password or modify password when needed.
  • Separate viewing and editing permissions with different password types.

Common use cases include mobile document protection, permission control before sharing, and storing private files on a personal device.
