With all of the attention, new consumer Zoomers, and the increased use of Zoom for large public meetings, we began to see uninvited, offensive, and sometimes even truly evil people disrupting meetings. By and large, this wasn’t something we had experienced with our business-focused customers. Zoom already had built-in security features like passwords and waiting rooms, but they were not default or mandatory. We failed to set pre-configured security features for our new customers, especially for schools. Instead, we assumed they would understand our platform like our business customers understand our platform and customize these features themselves. Most schools were scrambling to quickly create their first-ever distance learning programs and did not have IT teams to help. As fast as we could, we put out blog posts, videos, and training guides to help new meeting hosts, especially teachers, understand how to set up secure meetings. We also made settings like passwords, waiting rooms, and limited screen sharing mandatory for K-12 accounts. We introduced new features like the Security icon to put all of these protections in one easy-to-find place. These settings, used together, should make it very hard for an uninvited guest to join a Zoom meeting.
