One-time email passcodes for external presenters in Teams events

Microsoft Teams will introduce one-time email passcodes to verify anonymous external presenters in events, rolling out from April to June 2026. Tenant admins can enforce verification policies, allowing organizers to control external presenter access by requiring sign-in or passcodes, enhancing event security and flexibility. One-time Email Passcodes provide a way for tenant administrators and event organizers to verify anonymous, external presenters invited to Microsoft Teams events. When enabled, anonymous external presenters are prompted to enter a one-time email passcode before joining an event and receive a Verified label next to their name after joining. External presenters with personal or work Microsoft accounts are asked to sign in to their account for verification instead of receiving a one-time email passcode.

This distinction allows organizers to restrict an event to invited external presenters or allow more flexibility by permitting uninvited users with the event link to join through the lobby. By default, the policy is set to None, allowing external presenters to join anonymously. When the policy is set to eOTP, all external presenters must verify their identity either by signing in with a Microsoft account or by entering a one-time email passcode.
