Simple Zoom Tips to Protect Your Online Meetings From Zoombombing

There have been reports of Zoombombinginternet trolls crashing and hijacking meetings. Here’s how you can protect your Zoom meetings from Zoom raiders.

Companies and organizations use Zoom, a video conferencing app, to communicate face-to-face, so business operations don’t stop even during the crisis. 

The Zoom user base has ballooned exponentially, and with that rise come trolls and woes (a.k.a zoombombers) that want nothing more than to interrupt online meetings and classes, a.k.a. Zoombombing.

What You Need to Know About Zoombombing


So what do zoombombers actually do? And how do they hijack Zoom meetings?

Zoom has made several security improvements since the rise of Zoombombers. However, some of these internet woes can still crash other people’s Zoom meetings by either entering random meeting IDs or using other’s personal meeting IDs posted online. 

Once they’re in, they disrupt online meetings by screen-sharing explicit and pornographic media, or conveying racial slurs and sexist remarks—yes, things that are absolutely obnoxious and offensive.

Zoom has been making regular updates to enhance the app’s security. Yet, that doesn’t give you an absolute guarantee that zoombombers cannot enter your online meeting. 

The good news is that Zoom has added features that add a layer of protection to prevent Zoombombing.

Protect Your Online Meetings From Zoombombing

Do not use your personal meeting ID

Each Zoom account has its own Personal Meeting ID or PMI. It’s like your Zoom phone number that you get once you sign up for an account. 

Your PMI is a handy tool. It makes recurring one-on-one meetings or with a small group more convenient. Your team can quickly access your meeting without looking for a new meeting link or login details.

The problem with PMI, however, is that because it’s your permanent ID, people who happen to get your PMI can crash into your meeting whenever they want to, especially when they know your meeting schedules. 

To prevent this from happening, make sure to choose the option where the Zoom app creates a unique meeting ID every time you schedule a meeting. 

On mobile phones, when selecting “New Meeting,” turn off the “Use Personal Meeting ID” option., then click Start a Meeting.

On your desktop, click the dropdown button in the “New Meeting” option, then tick off “Use Personal Meeting ID.”


Set a password

Another way to prevent Zoombombing is by setting a password to your online meeting. Zoom automatically generates your meeting password when you create a new meeting, or you can set it yourself.

On desktop, click the dropdown button in the “New Meeting” option, bring your cursor to your PMI, then select “PMI Settings” from the drop. The PMI Settings will pop out, allowing you to change the passcode. 

On mobile devices, you can set the password by creating a schedule meeting. Click “Schedule,” customize your meeting, then add your password. This also works on desktop. 

Enable Waiting Room

The Waiting Room feature is excellent at stopping Zoombombers from crashing your meeting. The hosts (and co-hosts) can see who seeks to enter the meeting—like a holding area. 

The host can then select only those who are invited to join the meeting and remove unwanted participants. Beware, though, as internet trolls might use familiar names to deceive you to allow them in your call.

Remove a participant

If, despite your unique meeting ID and password, a Zoombomber still happens to crash your meeting, use the Remove feature to kick the disruptor out. By default, the participants cannot enter your meeting again. 

Did you happen to kick a person out by mistake? You can let them join your meeting again by changing the settings in the web version. Sign in to your account, then go to Settings > Meeting > In-Meeting (Basic), then enable the setting “Allow removed participants to rejoin.”


Set Screen Share feature to “host only.”

Zoombombing is not something to take for granted. Zoom crashers often share unpleasant and sexually explicit images—it’s awful and disturbing. 

Make sure to set the screen share feature to “host only.” That way, participants cannot share their screens and cause interruptions in your meeting.

Disable annotation feature

Internet trolls who love to raid Zoom meetings are smart. If you disable the screen share feature, then they look for another way to interrupt your meeting. They might use the annotation feature to scribble over your presentation. They can draw nasty objects in Zoom, and all participants can see it. 

To avoid this, check the settings and make sure only the host has the privilege to use the annotation feature.


Take control of the mic

Do you have participants who intentionally make noises? As the host of the meeting, you can disable the audio setting of the attendees. 

Select the Participants button to open the Participants pane. At the bottom, click on more options represented by three dots (…). Toggle on the setting “Mute Participants upon Entry.” Then uncheck the setting “Allow Participants to Unmute Themselves.” 


You can encourage your participants to use the Raise Hand feature to speak or ask questions. They may also use the chatbox feature.

Lock your meeting

Another way to prevent Zoombombing is to lock your meeting. Once all the expected participants are in the meeting, you can lock the meeting room so no one can enter the call. 

Click Participants > More Options (…) > check Lock Meeting. 


More Tips to Prevent Zoombombing


Here are more practical and actionable steps to prevent Zoombombers from entering your meeting.

Do not share your meeting link on social media

Zoom crashers can usually hijack meetings by scouring the internet for meeting links, IDs, and passcodes. 

Instead of posting the meeting details publicly, send your invitation via email or personal message. It assures you that all the participants are only those whom you personally invited. 

Remind your attendees not to share the meeting details with others.

Take control of the chatbox

The host has full control of the chatbox. He can decide who can use the chat feature and how they can use it. 

Participants can send files, multimedia, and GIFs in the chatbox, and trolls may use this privilege to share obscene images or videos. 

Here are things you can do:

  • Control what they can send or
  • Manage who can chat

Here’s how to do the former:

  1. Open your account in the Web version.
  2. Go to Personal > Settings > Meeting > In-Meeting (Basics)

To do the latter:

  1. In your Zoom meeting, click Chat.
  2. Select More Options represented by three dots. 
  3. Then choose how participants can chat.

You can also change the chatbox settings in your account via the web version, so you don’t have to change the setting every time you create a meeting. 

  1. Open your account in the Web version.
  2. Go to Personal > Settings > Meeting > In-Meeting (Basics)
  3. Look for Private chat and disable it.

To do this, click Participants, then click the Camera icon beside the participant’s name.
