WhatsApp users can now send self-destructing voice messages

WhatsApp expands “view once” feature for audio messages, allowing users to send messages that disappear after being listened to. This feature is useful for sharing sensitive information like credit card details or sending surprise messages. View once voice messages are marked with a one-time icon and can only be played once. All personal messages, including view once voice messages, are end-to-end encrypted. To send a view once voice message, open a chat, lock the recording, enter view once mode, and send. Recipients must have read receipts enabled to see if the message was opened.
