Hello Dongryeong Kim
Thank you for posting in Microsoft Community.
It seems like you have an issue signing out to OneDrive in your Windows 11 computer. Let’s work together in finding the best resolution to this issue.
For me to better understand the issue, I’d like to ask a few questions:
- What is the version of your OneDrive app?
To sign out of OneDrive on Windows 11 completely, please follow these steps:
- Right-click on the OneDrive icon in the system tray and select "Settings".
- In the "Account" tab, click on "Unlink this PC".
- Confirm that you want to unlink the PC from OneDrive.
- Next, open File Explorer and navigate to the OneDrive folder.
- Right-click on the OneDrive folder and select "Settings".
- In the "Account" tab, click on "Unlink OneDrive".
- Confirm that you want to unlink the OneDrive account from the PC.
After completing these steps, you should be signed out of OneDrive on your Windows 11 PC. If you want to prevent others from signing in with your Microsoft account without a password, you should ensure that your account is secured with a strong password and two-factor authentication.
Additionally, you should avoid sharing your account information with others and regularly monitor your account activity for any unauthorized access.
We look forward to your next response.
