WhatsApp is based on solutions adopted by other apps such as Telegram. In terms of "volatile" messaging, today it launches its own "View only once" function, which deletes photos or videos from the chat after they have been opened by the recipient.
How it works
When you send a photo or video on Whatsapp, you can view it only once and stop. As? Just tap the button with the number “1” to the left of the submit button. After the recipient opens it, the video (or photo) will be deleted forever, without any possibility of recovery.
Small but substantial note from your humble editor: the recipient on Whatsapp will still be able to see that the video or photo is of the disappearing type, so I still suggest using this feature only with people we trust, why do one screenshot is a snap.
Whatsapp worked quickly and (perhaps) well
The confirmation of the arrival of this new Whatsapp function was already there in June by the same Mark Zuckerberg, although details of when it would be released were scarce. According to the WaBetaInfo website, this feature has been in an internal test version for about a month already.
Possible suggested uses?
It goes without saying that the only real limit is your imagination, but to show how the function could be used, WhatsApp uses the example of sending a photo of sensitive information. For example a Wi-Fi password.
Of course, there are perhaps other much less "urban" uses for this type of functionality on the most popular messenger in the world. In any case, however, I find that it is useful to have an intermediate option between messages disappearing from the app (currently the specific option on Whatsapp makes them disappear only after a week) and remaining ad libitum in the chat.
