With ONLYOFFICE Docs, you can protect your docx files with a password so that no one is able to open the document without entering it.
Now, you need to enter the password every time you open the file for editing. If you want to co-author this document, tell the secret word to other collaborators.
If you want to create a new password or no longer need protection for a specific file, you can easily change or delete it.
Just go to the File tab -> Protect, and then choose the corresponding option.
You can also protect documents in ONLYOFFICE Desktop Editors on macOS, Windows, and Linux.
If you then upload a password-protected Word document created in ONLYOFFICE desktop to your online office, the protection will be preserved as well.
If a docx file is of a great importance for you, it is strongly recommended to save the password using any manager or memorize it, since there is no recovery option.
So, if you forget or lose the password, there is no possibility to restore or reset it and open the word file.
