Email OTP Verification coming to Teams Meetings

Microsoft introducing a new security feature in Teams that will enable enforcements of Email OTP verification for meetings. This new policy, "Anonymous users can join a meeting after verifying," will be available in the Teams Admin Center for all organizations. This feature is available only for meetings created by organizers with a Teams Premium license. The feature is in public preview, but should be rolling out in GA any time soon. The update will roll out automatically. Admins should consider to update the new meeting policy setting from “By e-mail code” to “No” by mid-February if they wish to continue blocking all unverified users (If "No" is the current setting). The policy is described in this article .

Join Teams work meetings from Microsoft Teams (free) and vice versa

Microsoft Teams (Free) users can currently join Teams for work (or school) meetings only as guests, which requires them to use a browser and results in a sub-optimal experience. The new feature rolling out will allow these users to join Teams for work (or school) meetings in one click, without being redirected to the browser or asked to fill in their name/surname. They will also be able to continue collaborating with the meeting organizer and other participants via meeting chat after the meeting. 

The feature will work in the opposite way as well, so Teams for work (or school) will just as easily be able to join meetings hosted by a Teams Free user with one click.
