About This Feature
Overview
Document Encryption is a built-in security feature in WPS Office for iOS that helps you add password protection to presentation files and reduce the risk of unauthorized access or modification.
Core capabilities include:
- Set a password for a new or existing presentation: add an open password to control who can view the file.
- Manage existing encryption settings: turn off or adjust an existing open password or modify password.
- Separate viewing and editing permissions: set an open password and a modify password for shared files.
This feature is useful for internal presentations, training decks, class materials, and presentation files that contain sensitive information.

Compare with Alternatives
| Dimension | WPS | Microsoft | Notion | Adobe | |
|---|---|---|---|---|---|
| Capability Summary | In iOS presentation files, WPS provides a Document Encryption entry from the top-right menu and supports both an open password and a modify password. | Microsoft Word officially supports password protection for documents. On macOS, Word can set a password to open or modify a document, while Word for the web cannot password-encrypt a document. | Google Docs does not currently support direct password protection for native Docs files and mainly relies on account security and sharing permissions. | Notion states that pages cannot be password-protected at this time and access is managed through private sharing or invitations. | Adobe Acrobat officially supports adding passwords to PDFs for viewing or editing restrictions, with a focus on PDF protection. |
| WPS Advantages | Advantage: WPS lets you set both an open password and a modify password directly inside an iOS presentation workflow, which is convenient for mobile document protection. | Compared with WPS: the official guidance focuses on Word documents, and Word for the web cannot directly password-encrypt files. | Compared with WPS: Google Docs does not provide a native per-document password feature for Docs files. | Compared with WPS: Notion focuses on page sharing permissions rather than page password protection. | Compared with WPS: Acrobat is stronger for PDF security, while WPS is more direct when you need to protect the original presentation file on iOS. |

Overall Conclusion: If you need to password protect a presentation file directly on an iPhone or iPad, WPS offers a more direct in-app workflow. Microsoft and Adobe also provide password protection, but their official guidance is centered on desktop Word files or PDF files, while Google Docs and Notion focus more on account access and sharing permissions.
Use Cases
| # | Scenario | Target Users | Core Pain Point | Solution |
|---|---|---|---|---|
| 1 | Share internal presentation materials | Employees, project owners | A presentation may be viewed by unintended people after sharing | Add an open password before sharing the file |
| 2 | Control editing permissions in collaboration | Team members, instructors | Others may open the file but should not edit it freely | Set a modify password to separate viewing and editing rights |
| 3 | Protect sensitive files on mobile devices | iPhone and iPad users | Files may be opened directly when a device is temporarily used by someone else | Encrypt the document on iOS before saving it |
| 4 | Send courseware or training decks | Teachers, trainers | It is hard to control file access after sending materials out | Share the file and send the password separately |
| 5 | Manage an already encrypted file | Users who already set a password | Existing password settings need to be updated or removed | Open Document Encryption and adjust the current password settings |
