Fix Word Password Protection Not Working in Microsoft 365
Question details
The user needs to properly password-protect a Word document to prevent unauthorized access.
- Product
- Microsoft Word (Microsoft 365)
- Device & OS
- not provided
- Scenario
- Attempting to secure a Word document with a password so unauthorized users cannot open it.
- Observed behavior
- The document opens without requesting a password on multiple computers, despite appearing to be password-protected through the Save As options.
Ensure you are saving the document locally or to a secure cloud folder before applying encryption, and verify that you have full editing permissions for the file.
Use the Encrypt with Password Feature in Info Settings
Instead of relying on Save As options or editing restrictions, use the dedicated document encryption feature in the File menu to require a password to open the file.
Many users confuse 'Restrict Editing' or legacy 'Save As' options with full document encryption. To prevent a file from being opened entirely, you must use the native 'Encrypt with Password' functionality built into Microsoft 365.
Open your Word document, click on the 'File' tab in the top-left corner of the window, and select 'Info' from the left-hand menu.
Click the 'Protect Document' button to reveal a drop-down menu, then choose 'Encrypt with Password'.
In the dialog box that appears, type your desired password and click 'OK'. You will be prompted to re-enter the password to confirm it. Type it again and click 'OK'.
Return to your document and save the file (Ctrl + S) immediately. The password protection will not take effect until the document is saved.
Close the Word document completely and reopen it. You should now be prompted to enter the password before the contents are displayed.
Encrypt Your Documents Easily with WPS Office
WPS Office provides a straightforward and highly secure way to encrypt your text documents, spreadsheets, and presentations. It fully supports Microsoft Word formats, ensuring your encrypted files remain secure and compatible across different platforms without complicated steps.
- 1. Open your document: Launch WPS Writer and open the document you wish to protect.
- 2. Navigate to the Protect tab: Click on the 'Protect' tab located on the top ribbon.
- 3. Select Encrypt: Click on the 'Encrypt' button to open the encryption settings dialog.
- 4. Set your passwords: Enter a password in the 'Document password' field to restrict opening, or in the 'Password to modify' field to restrict editing.
- 5. Confirm and Save: Click 'OK' and then save your document to apply the security settings.
Frequently Asked Questions
Why doesn't the 'Restrict Editing' password stop people from opening my Word document?
The 'Restrict Editing' feature is designed to prevent users from making changes, formatting, or copying content; it does not encrypt the file to prevent it from being opened. To block unauthorized viewing entirely, you must use the 'Encrypt with Password' feature instead.
Can I remove the password protection from my Word document later?
Yes. Open the document using your current password, go to File > Info > Protect Document > Encrypt with Password, delete the password from the text box so it is blank, click OK, and then save the document.
Are password-protected Word documents secure if I send them via email?
Yes, encrypting a document with a password in Microsoft 365 or WPS Office secures the contents using strong AES encryption. However, to maintain security, you should share the password with the recipient securely through a different channel, such as a text message or phone call, rather than in the same email as the attachment.
