The spies in Mission Impossible always received their instructions as audio and video messages that self-destructed a few seconds after listening. Now you can do the same with WhatsApp voice messages.

The latest update to the messaging service has activated the "single view" option for voice notes sent by the platform. Once the message is heard, it disappears and is no longer available to the receiver.

It's a similar option to photos and videos on the platform since 2021 and, as in these cases, the audio files received are not stored in the phone's memory. The limits of the feature are similar as well. You can only tell if the recipient has opened the voice message if they have read receipts enabled, and if the messages are not heard within 14 days, they disappear.

"When you want to read your credit card details to a friend or when you're planning a surprise, you can now also share sensitive information through voice messages with greater peace of mind," Meta explains.

How to activate it

The feature will be activated over the next few days for all users and is accessed with a new icon that looks like it is in the voice message recording tool.

When you turn on recording and swipe up to keep the microphone active, there is now a small icon with a number 1 next to the visual representation of the voice memo. Pressing it activates the one-time display feature and a message on the screen reminds the user that they are sending audio that will be destroyed once opened.
