How to Fix OneNote Rejecting the Correct Password for Protected Sections

Product: Microsoft OneNote
Device & OS: Windows 10, Mobile
Scenario: Unlocking a password-protected section synced via OneDrive on both a desktop and a mobile device.
Observed behavior: OneNote repeatedly displays an incorrect password error message for a previously accessible protected section, blocking access to the notes.

Before you start

Before troubleshooting, verify that your keyboard layout has not accidentally changed, as this can cause you to type different characters than expected.

Solution 1Recommended

Verify Password Input and Re-sync Microsoft Account

Perform fundamental password casing checks and refresh your Microsoft account connection to resolve temporary authentication glitches.

OneNote passwords are strictly case-sensitive. Often, an incorrect password error stems from a simple typing error or a desynchronized account state between your device and OneDrive.

Check capitalization and typing

Ensure Caps Lock is turned off. Type your password carefully into a visible text editor (like Notepad) to verify the correct casing and characters, then copy and paste it into OneNote.

Sign out of your account

In the OneNote desktop application, click on your profile picture or go to File > Account, select your Microsoft account, and choose 'Sign out'.

Sign back in

Restart the OneNote application and sign back into your Microsoft account to force a fresh connection to OneDrive.

Attempt to unlock

Navigate to the protected section, click to unlock, and paste the verified password.

Verify Password Input and Re-sync Microsoft Account

No Password Recovery Available: Microsoft cannot recover or reset a forgotten password for protected OneNote sections. If the password is truly lost, the data cannot be retrieved.

Frequently Asked Questions

Can Microsoft support reset my OneNote password if it stops working?

Why does my correct password work on my PC but not on my mobile phone?

This is typically caused by synchronization delays. Your mobile app might be trying to unlock an older, cached version of the section. Force a manual sync on both your PC and mobile device to resolve the discrepancy.

Are OneNote section passwords case-sensitive?

Yes, OneNote passwords are strictly case-sensitive. Always verify that Caps Lock is off and that you are capitalizing the exact characters used when originally setting up the password protection.

Does OneNote permanently lock the section after too many incorrect password attempts?
