Protect Selected Writer Text with a Section Password

Use a protected section when you want a specific part of a Writer document to be read-only unless someone knows its password. Select or create a section around that text, enable both Protected and With password, and store the password safely; this prevents ordinary edits, but it does not encrypt the document or hide its contents.

What does a section password protect?

A section is a named region of text inside a Writer document. Section protection makes that region resistant to editing and requires the password to remove its protection or change protected settings. It is useful for keeping approved wording, instructions, or a finalized clause from being changed by accident while leaving the rest of the document editable.

It is not a confidentiality feature. The LibreOffice Help page explicitly describes section protection as a switch against accidental changes, not information security. Readers may still see the text. If you need to stop people from opening or reading the file, use document encryption instead: for an OpenDocument file, choose File > Save As and select Save with password. These are different controls with different jobs. Review LibreOffice’s Writer protection guidance and its document-password help before choosing.

How do you protect new text with a password?

1. Select the exact text. In Writer, drag across the paragraphs you want to lock. Include the complete paragraphs and any headings that should be part of the protected block. Do not select surrounding content that other people need to edit.
2. Make the selection a section. Choose Insert > Section. In the dialog, give the section a recognizable name, such as “Approved policy text.” A useful name makes it easier to identify the correct region later. If you select only part of a paragraph, Writer converts that text into its own paragraph, so select complete paragraphs when you want the layout to stay predictable. See LibreOffice’s instructions for inserting sections.
3. Turn on both protection options. Under Write protection, select Protected and With password, then click Password…. Enter and confirm the password. Current LibreOffice Help specifies at least five characters; choose a longer, unique passphrase rather than relying on that minimum.
4. Apply the section and save. Confirm the password dialog, then click Insert in the section dialog. Save the document in its working format. Keep the password in an approved password manager or another secure place; LibreOffice cannot recover a forgotten section password for you.

How do you password-protect a section that already exists?

If the text is already a section, you do not need to create another one. Choose Format > Sections, select the section by its name, and enable Protected and With password under Write protection. Click Password…, enter and confirm the password, then apply the change. The official Editing Sections instructions describe selecting a section from this dialog and changing its protection.

Afterward, reopen Format > Sections and check the section list. LibreOffice shows a closed lock beside a protected section. If you do not see the section, check that you selected the intended name and that the text was actually made into a section rather than merely highlighted.

How do you test or remove the protection?

Save the file, click inside the protected text, and try to make a harmless change. Writer should prevent the edit or show a warning. Then try editing a paragraph outside the section; that text should remain editable. This two-part check catches both a section that was never protected and a selection that accidentally included too much of the document.

To make a later change, choose Format > Sections, select the locked section, clear Protected, and enter the correct password when prompted. Apply the change, edit the text, and restore protection afterward if the section should remain locked. To change the password without removing the section, use the same dialog’s Password… control and enter the current password followed by the new one as prompted. Do not remove or recreate the section unless you intend to change its structure.

What should you check before sharing the document?

• Confirm the locked text is in a section and the section list shows a closed lock.
• Test that text inside is blocked while text outside remains editable.
• Save, close, and reopen the file, then check the protection again.
• If recipients will use a different office suite or a converted format, test a copy in that workflow. Section behavior can vary across file formats and applications, so do not assume this is access control.
• Use Save with password when the goal is to restrict opening or reading an OpenDocument file. Do not mistake a section password for document encryption.

As of October 9, 2026, the current LibreOffice Help documents section passwords, the five-character minimum, the closed-lock indicator, and the separate Save with password option. Menu wording can vary slightly by version or operating system, but the reliable outcome is the same: only the named section is protected, the rest remains usable, and a password is required to turn that protection off.
