Below are the steps.

4. Enter the password and confirm it. Click OK.
This section will be immediately protected and locked. The information in it will be hidden and not searchable. You will only see a “This section is password protected” message. If sync is turned on, you will find that this section is also protected elsewhere.
To unlock the section, press the Enter key. In the Protected Section dialog that appears, enter the password. And the section will be unlocked and accessible as usual.
To make the password protection more effective, OneNote will automatically lock an unlocked section if it is inactive for a while. You can customize the amount of time. Before you step away from your computer, you can lock all the protected OneNote sections immediately by going to the Password Protection screen and then clicking Lock All or by using the shortcut CTRL + ALT + L.
