About This Feature
Overview
Document Encryption is a built-in document security feature in WPS Office for iOS. It helps protect document content with passwords. After you turn on document encryption, you can set an open password and a modify password separately.
Core capabilities include:
- Encrypting a new or current document by opening Document Encryption inside the file and turning on the Password Encryption switch.
- Managing existing encryption settings by turning off or adjusting the open password and modify password.
- Using two password types: an open password for viewing the file and a modify password for editing the file.
This feature is useful for personal files, work drafts, and shared documents that need extra protection. Keep your password in a safe place. If you forget it, the document cannot be opened.

Compare with Alternatives
| Dimension | WPS | Microsoft | Notion | Adobe | |
|---|---|---|---|---|---|
| Capability Summary | In a document on iOS, WPS provides a Document Encryption entry with password encryption and supports separate open and modify passwords. | Word supports password protection for documents. On macOS, it can set a password to open, modify, or both, while Word Online cannot password-encrypt a document. | Google Docs does not provide a password option for a single document. Its official encryption workflow is Workspace Client-side encryption managed by an admin for organizational use. | Notion supports sharing and access control for pages, but its official help page says password protection for a page is not available at the moment. | Acrobat supports setting a password for viewing or editing a PDF and offers more detailed PDF protection options. |
| WPS Advantages | Advantage: You can set open and modify passwords directly inside the document on iOS. Distinct: The workflow is more direct for everyday document password protection on mobile. | Compared with WPS: Microsoft documents focus more on desktop workflows, and Word Online has clear limits for password encryption. | Compared with WPS: Google focuses more on organization-managed encryption and account-based access instead of a single-document password entry. | Compared with WPS: Notion focuses on publishing and permissions, not document password protection. | Compared with WPS: Adobe is stronger for PDF security management, while WPS is more direct for regular document protection inside a document workflow. |

Overall Conclusion
If you want to password protect documents on iPhone in a direct mobile workflow, WPS keeps the entry point and setup steps more centralized. Microsoft and Adobe also support password protection, but they are more tied to desktop document workflows or PDF-focused scenarios. Google and Notion rely more on account, permission, or organization-level controls.
