Hi Brittany,
Thanks for posting in the community. We are happy to help you.
According to your description, do you mean the account is signed in and you want to remove it from OneNote? Or do you mean it's stuck at the login window, and you can't change the account username?
If you mean the account is signed in and you want to remove it, please try the following steps.
- In OneNote, select the Notebooks tab at the bottom of the app, then click the three points in the upper right corner> Settings.
- Select Account, then select "Sign out of OneNote".
If you mean it's stuck at the login window and you can't change the account username, please totally quit OneNote, then relaunch it and check again. If the situation still happens, please uninstall OneNote, then reinstall OneNote from Google Store and check again.
We look forward to your response. Thanks for your cooperation.
Sincerely,
George | Microsoft Community Moderator
