Reset the Fingerprint Unlock Feature in OneNote

Disabling and re-enabling the biometric settings within the app can clear authentication glitches caused by recent app updates.

Often, a simple toggle of the security settings forces the application to re-register the connection with your device's biometric hardware.

1
Access OneNote Settings

Launch the OneNote app on your mobile device and navigate to the app's Settings menu.

2
Disable Fingerprint Unlock

Locate the privacy or security section within the settings and toggle off the 'Fingerprint Unlock' option.

3
Re-enable Fingerprint Verification

Close and reopen the app, return to the same security menu, and toggle 'Fingerprint Unlock' back on. You will be prompted to verify your fingerprint to save the configuration.

Tip: Performing a soft restart of your phone between disabling and re-enabling the feature can help clear temporary system caches.

Frequently Asked Questions

Why did OneNote suddenly stop accepting my fingerprint?

This typically happens after a recent app update or device operating system update, which can disrupt the communication between OneNote's internal security module and your phone's biometric hardware.

Will reinstalling OneNote fix the fingerprint unlock issue?

Reinstalling the app may not always resolve the issue if the bug is rooted in a recent system update or cached authentication tokens. Manually resetting the fingerprint feature in the app settings is often a more effective first step.

How do I report an ongoing app bug to Microsoft?

You can report unresolved issues by navigating to OneNote Settings, selecting 'Help & Feedback', and choosing the option to send feedback directly to the Microsoft development team for review.
