How to Identify Unknown OneDrive Security Accounts by Name
Question details
Users want to view descriptive, human-readable account names instead of raw security identifiers in their folder properties.
- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- Checking the advanced security permissions for the OneDrive installation folder.
- Observed behavior
- The Windows Advanced Security Settings display raw SIDs (such as S-1-15-3 and S-1-15-2) rather than clear, descriptive user or application names.
Before attempting to modify any folder permissions, ensure you are logged into Windows with an Administrator account, as viewing or altering advanced security properties requires elevated privileges.
Submit a Feature Request via the OneDrive Desktop Client
Because the display of AppContainer SIDs is a default Windows behavior, the recommended approach is to submit a direct feature suggestion to the OneDrive development team to improve the UI.
The SIDs (S-1-15-2 and S-1-15-3) are standard Windows identifiers used for managing AppContainer permissions for Universal Windows Platform (UWP) applications. Since the operating system currently fails to resolve these into friendly names in the security tab, providing feedback helps prioritize a fix.
Click on the OneDrive cloud icon located in the Windows taskbar notification area (system tray), then click the gear icon in the top right corner of the flyout menu.
From the dropdown menu, select the 'Send feedback' option.
Choose 'I have a suggestion' and describe your request clearly, asking the development team to display descriptive account names instead of raw SIDs like S-1-15-2 and S-1-15-3 in the OneDrive folder security settings.
Post in the Microsoft Feedback Community Portal
You can also voice your concern on the official Microsoft Feedback Portal, where other Windows users experiencing the same issue can upvote your request.

Frequently Asked Questions
What do the security identifiers S-1-15-2 and S-1-15-3 mean?
These are AppContainer Security Identifiers (SIDs) used natively by Windows. 'S-1-15-2' represents all app packages, while 'S-1-15-3' represents all restricted app packages. They ensure that built-in apps, like OneDrive, have the correct restricted access to system files. Windows sometimes fails to translate these technical codes into readable names in the properties menu.
Is it safe to delete the unknown account SIDs from my OneDrive folder permissions?
No, it is highly recommended that you do not delete or modify these SIDs. Removing these permissions can break the synchronization functionality of OneDrive or cause errors with other built-in Windows applications that rely on AppContainer security protocols.
Can I manually rename these SIDs to friendly names in Windows?
Unfortunately, Windows does not provide a built-in feature to manually rename or alias SIDs within the Advanced Security Settings interface. The translation of SIDs to friendly account names is handled entirely by the operating system's internal processes.
