Scenario: Reinstalling the OneNote application on a Samsung Android device and finding it still logged in.

Solution 1Recommended

Unlink Your Microsoft Account from Samsung Device Settings

Removing the Microsoft account link from your phone's system settings prevents apps like OneNote from using saved system credentials automatically.

Samsung devices often link your Microsoft account at the system level to enable features like OneDrive backup and cross-device syncing. Because this linkage exists outside the OneNote app, simply uninstalling the app will not remove the login credentials from your phone.

Open Device Settings

Unlock your phone, locate the gear icon, and open the Settings app.

Access Accounts and Backup

Scroll down the settings menu and tap on 'Accounts and backup', then select 'Manage accounts'.

Remove the Linked Microsoft Account

Find your Samsung account or the specific Microsoft account in the list, tap on it, and select 'Remove account' to unsync the credentials from your device.

Unlink Your Microsoft Account from Samsung Device Settings

Account Unlinked: Once unlinked, reinstalling Microsoft apps will require you to manually enter your password.

Solution 2

Revoke OneNote Access via Microsoft Account Management

You can remotely revoke OneNote's permission to access your Microsoft account to ensure it prompts for a password upon reinstallation.

Solution 3

Change Password and Enable Two-Step Verification

If you suspect unauthorized access, changing your password and enabling two-factor authentication (2FA) will immediately invalidate all active sessions.

Frequently Asked Questions

Why does Android save my Microsoft account credentials?

Android devices, particularly Samsung phones, often integrate Microsoft accounts directly into the system settings to provide seamless features like gallery sync with OneDrive. This causes your login credentials to be stored at the system level rather than just within individual apps.

Does clearing OneNote's app data sign me out completely?

Clearing the app data removes local files and cache within the OneNote app itself. However, if your Microsoft account is synced to the Android system settings, OneNote will automatically pull those credentials again upon reopening, bypassing the login screen.

Can I use Microsoft apps on Android without an account?

Most cloud-based Microsoft apps, including OneNote and OneDrive, require you to sign in with a Microsoft account to function and sync your files across devices. Local-only usage is extremely limited.

Will changing my Microsoft password log me out on my phone?

Yes, changing your password will invalidate existing login tokens. Any connected apps, including OneNote, will be forced to prompt you for the new password upon their next sync attempt.
