Can You Identify Who Password-Protected a OneNote Section?

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Collaborating on a shared notebook and encountering a password-protected section without knowing who locked it.
Observed behavior: The user is unable to access a password-protected section and cannot find any system history or log indicating which author applied the lock.

Before you start

Before proceeding, verify if you are using a shared notebook, as password protection is typically applied by notebook owners or authorized editors. Ensure you have an active communication channel with your team members.

Understand OneNote's Password Tracking Limitations

Microsoft OneNote does not natively track or display the specific user who applied a password to a section.

Unfortunately, OneNote does not provide a feature, history log, or metadata property that identifies who password-protected a section. Once a password is set, the application does not expose the history of that action.

The password could have been applied by the notebook owner or any authorized author with editing permissions. To resolve the lockout, you must manually identify and communicate with your collaborators.

Identify notebook collaborators

Click the 'Share' button in the top right corner of the OneNote application to view the list of people who have editing permissions for the notebook.

Contact authorized editors

Reach out to the notebook owner or other collaborators who have edit access to ask if they set the password and can provide it to you.

No Password Recovery: Microsoft cannot recover forgotten OneNote passwords. If the password is lost and no collaborator knows it, the section cannot be unlocked.

Frequently Asked Questions

Can Microsoft Support help me recover a OneNote section password?

No, Microsoft Support cannot unlock or recover passwords for protected OneNote sections. If you or your team lose the password, the data in that section will remain completely inaccessible.

How do I remove a password from a OneNote section if I know it?

To remove a password, right-click the protected section tab, select 'Password Protect this Section', and then click 'Remove Password' in the Password Protection pane. You will need to enter the current password to confirm the removal.

Does OneNote's page version history show who locked the section?

No, the 'Page Versions' feature only tracks changes to the content of the pages, such as text edits or added images. It does not record administrative actions like who applied section-level passwords.
