How to fix Teams error code 2148073494 in Windows?

Teams error code 2148073494 is a common issue that appears when users attempt to log into Microsoft Teams, especially in work or school accounts. This error generally signals a problem with account authentication, often linked to account credentials, network restrictions, or corrupted components in Windows Account Manager (WAM), which is essential for secure sign-ins. When Teams encounters error code 2148073494, users may be unable to access their accounts, and the app might prompt them repeatedly for sign-in attempts.

Several factors contribute to Teams error code 2148073494. Corrupted credentials stored in Windows Credential Manager can cause Teams to continually request logins. Additionally, third-party security software or VPNs can interfere with the authentication process.

Additionally, outdated Windows Filtering Platform (WFP) drivers associated with security software might block essential WAM operations, leading to repeated sign-in errors.

To resolve Teams error code 2148073494, users can attempt to clear cached credentials, temporarily disable VPNs, or reinstall Windows Account Manager plugins to restore functionality. Disconnecting and reconnecting work or school accounts through Windows settings has also proven effective in resetting account permissions.
