You can encrypt OneNote sections with passwords – here's how on Window 10.

You can protect sections of OneNote with passwords to add an extra layer of security, and in this guide, we'll outline the steps to complete the task.

On Windows 10, if you use the desktop version of OneNote, you can password protect sections for an extra layer of privacy to prevent other people from accidentally accessing certain notes with sensitive information.

Although the ability to protect your notes using a password is a useful feature, it's been designed to encrypt sections, not the entire notebook, and protected notes won't appear in searches. You can also use different passwords for each section, but you have to make sure to remember your passwords. If you forget your passwords, you won't be able to access your notes, even if you have a Microsoft account to access your OneNote notebooks.

In this Windows 10 guide, we'll walk you through the steps to protect OneNote's sections with passwords. In addition, we'll also outline the steps to use a protected section as well as manage password settings.
