The coronavirus pandemic has not only been a disruptive time for many business meetings, but also a vulnerable one. With many confidential business meetings happening over Zoom, many organisations are quite sceptical and terrified regarding the security of these Zoom meetings.

To brief up, since hackers have found ways to enter a Zoom meeting without being invited, there are chances that any important organisational information could leak out through distrustful connections. Or, any attendee of the meeting could potentially leak confidential matters being discussed in it.

Use this tip to save the panic and safeguard both company policies and your crucial meeting minutes.

What is an Audio Watermark in Zoom Recordings?

An Audio Watermark is an embedded reserve of personal information of meeting attendants who record a business call or meeting. The audio watermark would not be visible nor audible to any user and would be entirely accessible for Zoom alone. Nonetheless, the audio watermark would work if the option of allowing only “signed-in” users is enabled.

Audio watermarks embed a user’s personal Zoom details as and when a call is recorded. If this recorded meeting is shared or leaked without permission in any way, the admin or the meeting host could request Zoom to expose the personal information of the recorder by looking into the audio watermark of that recording.

However, the recording file sent to Zoom to investigate the audio watermark must be at least 2 minutes for Zoom to retrieve personal information.

How to Enable ‘Add Audio Watermark’ in Zoom Recordings

Before proceeding, ensure that you have logged in as an ‘Admin’ within a given company or organisation. If yours is a Basic Zoom Account, then the settings required to Add Audio Watermark would be missing.

Go to and sign in with your admin Zoom account. Then, expand the ‘Account Management’ options beneath the ‘Admin’ section on the left panel and select ‘Account Settings’ option.

Scroll down to find an option that says “Only authenticated users can join meetings”. This needs to be enabled to be able to enable ‘Add Audio watermark’ feature. Click the toggle bar next to this option and ensure that it turns blue and does not remain grey.

Optionally, you could also add more “Meeting Authentication Options” such as “Only signed-in users can join meetings” and “Only signed-in users with a specific domain can join meetings” by clicking the “Add Configuration” button. These domains could be restricted to your company email IDs or any such private business domains.

Finally, enable the ‘Audio Watermark’ feature by scrolling down a bit on the same page until you see an option called ‘Add Audio Watermark’. Enable this setting by switching the toggle bar beside it to blue. If you get a confirmation dialogue box, be sure to click on the ‘Turn On’ button.

Once you’re done, click on the tiny lock icon next to a setting to secure your changes. This would make sure that no one on your account can make any further changes and these settings would also be sealed for groups too.

This little precaution can help make Zoom business meetings a much safer and trusted platform.
