View once messages are designed to give users more control over their privacy and ensure that the messages they send are not shared with anyone else. When a view once message is sent, the recipient will be able to view it once, after which it will be deleted from their device.
To send a view once message, users simply need to go to the chat window with the person they want to send the message to, and then select the "view once" option from the menu. They can then type their message and send it as they normally would.
When the recipient receives the message, they will see a notification that they have received a view once message. They can then open the message and view it, after which it will be deleted from their device.
View once messages can be useful in a variety of situations. For example, if you want to send someone a sensitive piece of information that you don't want them to share with anyone else, a view once message can help ensure that the information remains private. It can also be useful for sending temporary messages or information that may become irrelevant after a short period of time.
Overall, the view once message feature on WhatsApp is a useful tool for users who want to have more control over the messages they send and ensure that they are not shared with anyone else. It provides an additional layer of privacy and security for users, making it an important feature for those who value their privacy online
