This means only people who know the password can open them, protecting sensitive notes without locking your entire notebook. Setting a password on a OneNote section is simple, and you can change or remove it later if needed. ## What you need to know before password protecting a OneNote section Password protection on sections is only available in OneNote for Windows 10 (the UWP app) and OneNote 2016 for Windows. It isn’t supported in the OneNote web app or the Mac version at this time. Make sure your notebook is saved locally or synced to OneDrive because password protection works only on sections stored in these locations. Password protection applies only to individual sections, not to entire notebooks or individual pages. You’ll have to set a password for each section you want to protect separately. Also, keep your OneNote app updated to the latest version to [access all password-related features](https://dailyhassle.com/secure-data-microsoft-office-365/). ## How do I password protect a section in OneNote? Follow these steps on Windows to add a password to a OneNote section: 1. Open OneNote and go to the notebook with the section you want to protect. 2. Right-click the tab of the section you want to lock. 3. Choose "Password Protect This Section" from the menu. 4. In the sidebar that appears on the right, click "Set Password." 5. Enter a strong password in both fields and confirm it. 6. Click "OK" to apply the password. Once set, the section locks automatically after a short period of inactivity. You can also lock it manually whenever you want. If you use OneNote on a Mac or the web, password protection isn’t available, so you won’t find these options. ![A user right-clicking on a OneNote section tab to access the password protect menu.](https://tse1.mm.bing.net/th?q=OneNote%20section%20tab%20right-click%20menu%20with%20password%20protect%20option%20photo&w=624&h=352&c=7) ## How can I change or remove the password from a OneNote section? To change or remove a password on a OneNote section in Windows: 1. Open OneNote and find the notebook with the protected section. 2. Right-click the password-protected section tab. 3. Select "Password Protect This Section." 4. In the sidebar, click "Change Password" to update it. 5. Enter the current password, then enter the new password twice. 6. To remove the password, click "Remove Password" instead. 7. Enter the current password to confirm removal. Removing the password makes the section accessible to anyone who can open the notebook, so be certain you no longer need protection before removing it. ![OneNote app open on a laptop screen showing the option to remove or change a section password.](https://tse1.mm.bing.net/th?q=OneNote%20app%20password%20removal%20option%20on%20Windows%20laptop%20screen%20photo&w=624&h=352&c=7) ## What happens if I forget my OneNote section password? If you forget the password for a protected section, Microsoft doesn’t offer a way to recover or reset it. The password is designed to secure the section, so without it, you can’t access its contents. To avoid losing access, keep a secure record of your passwords outside OneNote. If you lose the password, your only option to recover the content is to restore an unprotected backup of the notebook made before the password was set. Regularly back up important notebooks, especially if you use password protection on sections with critical information. ## Limitations and security considerations of OneNote password protection Password protection in OneNote encrypts the contents of individual sections within the app, helping to keep your notes private. However, it’s not the same as full-disk encryption or advanced security software. Because password protection works only on sections, other parts of your notebook remain accessible. Also, this feature is unavailable on Mac and web versions, so if you access your notebooks there, those sections won’t be protected. Finally, if you share a notebook, anyone with access to the password-protected sections can open them, so handle passwords carefully. For highly sensitive information, consider additional security measures beyond OneNote’s built-in protection. ## Conclusion Setting a password on a OneNote section keeps your sensitive notes secure from casual access. Remember to keep track of your passwords since there’s no recovery if you forget them. You can always change or remove these passwords as your needs change, giving you control over who sees what without locking down your entire notebook. ## Frequently Asked Questions ### Can I password protect entire notebooks in OneNote? No, OneNote only allows password protection on individual sections, not entire notebooks. ### Is password protection available on OneNote for Mac or the web? No, currently only OneNote for Windows 10 and OneNote 2016 support password protection on sections. Mac and web versions don’t have this feature. ### Will password protecting a section encrypt the data? Yes, password protection encrypts the section's content within OneNote. However, it’s not the same as full-disk encryption, so for very sensitive data, consider additional security measures.
