What Zoom settings should users (hosts) apply to secure virtual meetings/classrooms?

We recommend that users familiarise themselves with all the available Zoom security features that they can apply to have safe online meetings.

It is also recommended that users are using the latest Zoom software. Find out more about how to update your Zoom software.

When a user (host) schedules a Zoom meeting, it is recommended to
