|---|---|---|---|---|---|
| Capability Summary | WPS Presentation on Windows lets you set a password for a presentation file from the File menu or from File > Options > Security. | Word desktop supports password encryption through File > Info > Protect Document > Encrypt with Password, while Word Online cannot password-encrypt or edit a password-encrypted document. | Google Docs does not currently support password protection for an individual document and relies on account security and sharing permissions instead. | Notion does not currently support password protection for a page and suggests private sharing with invited people instead. | Acrobat lets you protect PDF files with a password for viewing or editing and also offers additional PDF security options. |
| WPS Advantages | Advantage: It provides two direct entry points inside the presentation editing workflow and can be used without membership for this feature. | Compared with WPS: the official guidance is centered on Word documents, and the web version cannot encrypt or edit password-encrypted files. | Compared with WPS: there is no built-in per-file password entry for Docs, so access control is handled through account and sharing settings. | Compared with WPS: page sharing is permission-based rather than password-based for individual pages. | Compared with WPS: Acrobat offers deeper PDF security controls, but its workflow is focused on PDF files rather than native presentation editing. |

Overall Conclusion
If you want to add an opening password directly to a presentation file on Windows, WPS fits naturally into the presentation editing flow. Other products are better aligned with their own primary scenarios, such as online sharing controls or PDF-focused security settings.
