What Are Password-Protected Sections in OneNote 2013?

Password-protected sections in OneNote 2013 allow you to restrict access to sensitive information — like work notes, personal data, or confidential client details.

When you protect a section with a password, its pages become encrypted, meaning no one can view the content without entering the correct password.

This protection applies whether your notebook is saved locally or synced to OneDrive — making it a crucial security feature.

• ‍ Prevention of unauthorized access.

• ⚡ Quick protection without closing OneNote.
