Zoom is an easy-to-use videoconferencing tool with a generous free tier. With people around the world isolating indoors to protect themselves against the spread of the coronavirus, it has never been more popular.

But its popularity has also attracted trolls. The phenomenon of Zoombombing, in which an uninvited guest uses Zooms screen-sharing feature to broadcast porn and shock videos, has been on the rise. Most Zoom meetings have a public link that, if clicked, allow anyone to join. Trolls have been collecting these links and sharing them in private chat groups, and then signing on to other peoples calls to cause mischief.

Theres an easy way to stop this from happening, but Zoom makes it needlessly difficult to find. If you schedule a meeting from the web interface, you wont see the option to disable screen sharing. Instead:

  • Click on Settings in the left-hand menu
  • Scroll down to Screen sharing and under Who can share? click Host Only
  • Click on Save

Once you save your settings, future meetings that you start will have sharing disabled by default.

If you forget to change the setting before you start your meeting, theres a way to modify your settings after it starts:

  • Once your Zoom meeting is running, click the caret to the right of the green Share Screen button in the center of the bottom row of icons
  • Click Advanced Sharing Options...
  • A dialog box will pop up allowing you to switch screen sharing availability from all participants to the host only.

And what if youre creating a meeting from your mobile device?

To disable screen sharing after youve started your meeting:

  • Tap the More (...) button at the bottom right corner of the screen
  • Tap Meeting Settings
  • If youre using an iPhone, scroll down to Allow Participants to Share and switch the toggle off. If youre using an Android phone, find Lock Share and switch the toggle on.
