This means that you can open the app only if you have a motor or face-to-face when you protect your phone.
With this protection system, it is more difficult for anyone to access your conversations, but it is harder to do, because you ask the request to identify the branch or opponent each time You want to send someone's message.
The feature is very easy to be able: open the options for VhatsApp, go to the Privacy button and click on it. WhatsApp will ask you if you want the green phone to be activated immediately.
However, while the activity is opening the application's access, it is not a n; lock notice. This means that if someone is at your phone, they will still be able to see the messages when they come in and even They can answer them if they use the action prompt response.
