email passcodes

The email passcodes tag covers Microsoft Teams’ use of one-time email verification for anonymous external presenters in managed events. The feature provides an identity checkpoint for webinars, town halls, and similar events where outside speakers participate without joining the host tenant. Coverage focuses on how Teams administrators and event organizers can use verified email checks to distinguish an expected presenter from someone who simply has an event link. It also highlights the governance implications of adding a lightweight access control between open participation and fully authenticated membership, as well as the feature’s Microsoft 365 roadmap and Teams administration context.
