About This Feature

Overview

Document Encryption is a document protection feature in WPS Writer on Android. It helps protect document content by using passwords to control opening or editing access.

Core capabilities include:

Turn on password encryption for the current document and set separate passwords for opening and editing.
Change or clear passwords for an encrypted document when you need to manage access later.

This feature is useful for contracts, personal files, internal drafts, and other documents that need controlled access.

Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Supports password encryption in documents on Android, including separate passwords for opening and editing, plus ongoing password management.	Word officially supports setting or removing a password for a document, with document-level password protection described in its support article.	Google Sheets officially supports protected sheets and ranges, but its help page states that protected data cannot be secured with a password.	Notion officially provides page sharing, access scope, and permission levels, focusing on collaboration permissions rather than local document passwords.	Acrobat officially supports adding passwords to PDFs to limit opening or editing.
WPS Advantages	Advantage: You can set both open and edit passwords directly in a mobile document flow. Distinct: The same feature area also lets you change or clear an existing password.	Compared with WPS: the official Word article mainly describes a desktop File > Info path for password management.	Compared with WPS: Google officially notes that sheet protection should not be used as a security measure and does not support password protection for data in this workflow.	Compared with WPS: Notion focuses on page sharing and permission control instead of password encryption for local office documents.	Compared with WPS: Adobe password protection is centered on PDF files, which fits PDF-specific workflows.

Overall Conclusion
If you want to password-protect a text document directly on an Android device, WPS provides a workflow that is closely aligned with mobile document handling. Other products also offer protection features, but their official focus is more on desktop documents, online sharing permissions, or PDF protection.
