The user is unable to sign in to the personal OneDrive application on Windows because it prompts for an unknown PIN, despite web sign-in working correctly.

How to Fix Cannot Sign In to Personal OneDrive App on Windows

Product: OneDrive
Device & OS: Windows 11
Scenario: Attempting to sign in to a personal OneDrive account while a work OneDrive account is already logged in on the device.
Observed behavior: The OneDrive app requests an unknown PIN and prevents the user from accessing personal files, even though the credentials are correct and the system is updated.

Before you start

Verify that you can successfully log in to your personal OneDrive account via a web browser to confirm your credentials are correct before modifying app settings.

Solution 1Recommended

Reset OneDrive via Windows Settings

Resetting the OneDrive application clears its local cache and configuration, resolving unexpected PIN prompts and sign-in glitches without deleting your files.

Sometimes the Windows credential manager or the OneDrive local cache becomes corrupted, especially when juggling work and personal accounts. Resetting the app forces it to rebuild this configuration.

Open Windows Settings

Click the Start menu and select Settings, then navigate to Apps > Installed apps.

Locate OneDrive

Scroll down the list of applications or use the search bar to find Microsoft OneDrive.

Access Advanced Options

Click the three horizontal dots next to Microsoft OneDrive and select Advanced options.

Reset the App

Scroll down to the Reset section and click the Reset button. Confirm the action and allow the application to clear its data.

Data Safety: Resetting OneDrive will only reset the app configuration. It will not delete any of your synced files or cloud data.

Solution 2

Verify System Time and Reinstall OneDrive

If resetting does not work, incorrect system time could be causing authentication errors, or the application installation itself may be corrupted.

Frequently Asked Questions

Why does OneDrive ask for a Windows PIN instead of my password?

Windows 11 often defaults to Windows Hello (PIN) for authentication to enhance security. The PIN it is asking for is likely your local Windows user profile login PIN. If you don't know it, look for a 'Sign in with another method' or 'Use password' option on the prompt.

Can I run personal and work OneDrive accounts on the same computer?

Yes, you can link one personal account and multiple work or school accounts to the OneDrive desktop app simultaneously. You can add them by right-clicking the OneDrive cloud icon on your taskbar, clicking the gear icon for Settings, navigating to the Account tab, and selecting 'Add an account'.

What should I do if the Reset button is missing in Windows Settings for OneDrive?

If you cannot find the Reset button in Settings, you can manually reset OneDrive. Press Win + R to open the Run dialog, paste '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset', and press Enter. This will restart the app and reset its configuration.
