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.
