Question details

The user is encountering a sign-in error on OneNote for the web due to excessive authentication attempts and also needs instructions on how to move sections between notebooks, as the option is missing in the browser.

How to Fix OneNote Sign-In Error After Too Many Authentication Attempts

Product: Microsoft OneNote
Device & OS: Web Browser, Android
Scenario: Accessing OneNote via a web browser with multiple open tabs and trying to organize notebooks by moving sections.
Observed behavior: A server message blocks access, stating there are too many repeated authentication attempts. Furthermore, the Move and Copy Section commands do not appear when right-clicking in the web browser version.

Before you start

Make sure you temporarily close all active OneNote browser tabs to stop any ongoing background authentication requests before attempting to fix the issue.

Solution 1Recommended

Clear Browser Data and Use a Private Window

Use this method to clear out corrupted authentication tokens and bypass the sign-in loop preventing you from accessing OneNote.

Opening multiple notebooks in separate browser tabs can flood the server with login requests, triggering Microsoft's security blocks. Clearing your cache and cookies forces a clean session.

Close existing sessions

Close every browser tab or window that currently has OneNote or any Microsoft Office online application open.

Wait before retrying

Wait for about 5 to 10 minutes to allow the server-side authentication limits on your Microsoft account to reset.

Clear browser cache

Navigate to your web browser's history or privacy settings and clear your cookies and cached data, specifically for Microsoft domains.

Use Incognito mode

Open a Private or Incognito browsing window and attempt to log into OneNote on the web again.

Clear Browser Data and Use a Private Window

Limit Open Tabs: To prevent this error from returning, try to keep only one or two OneNote web tabs open at a time.

Solution 2

Use the Desktop App to Move Sections

Since the web browser version of OneNote restricts section management, use the desktop application to move or copy sections.

Frequently Asked Questions

Why am I getting a 'too many authentication attempts' error in OneNote?

This error is triggered when Microsoft's security servers detect multiple rapid sign-in requests. This is frequently caused by having multiple OneNote web tabs open simultaneously, which forces the browser to send repetitive sync and login requests.

Can I move OneNote sections using a web browser?

Generally, no. The 'Move or Copy Section' command is limited in the OneNote web app. To reliably move sections between notebooks, you must open your notebooks in the full Windows or Mac desktop application.

How do I move sections on my Android tablet or phone?

On supported mobile devices like a Samsung tablet, you can manage sections by long-pressing the section tab you wish to move. Once selected, look for the move/copy icon (usually a folder with an arrow) in the top menu and select your destination notebook.
