If you no longer need to protect a section in OneNote 2013 with a password, you can remove it. Removing a password makes the section available for viewing by anyone who has access to it. You must know the password to remove it from a section.
Right-click the tab of the section whose password you want to remove.
On the shortcut menu that appears, click Password Protect This Section.
In the Password Protection pane, click Remove Password.
In the Remove Password dialog box, type the password and click OK.
