MC1338817 — Microsoft Teams PowerShell: Web Account Manager (WAM) becomes the default authentication broker

MC1338817Microsoft TeamsplanForChangeUpdated: 3 June 2026

Microsoft Teams PowerShell module will use Web Account Manager (WAM) as the default authentication broker on Windows starting late June 2026 (version 7.8.1). A temporary -DisableWAM parameter allows bypassing WAM. Non-interactive and older Windows versions are unaffected. Admins should review and update scripts accordingly.
