Facebook has since confirmed that this is a characteristic now in testing and at an announcement made to Engadget, a Facebook spokesperson stated, “we would like to give people more options and controls to secure their personal messages, and lately, we started testing a feature which allows you unlock the Messenger program with your device’s preferences.”
In case you do not find the attribute available for you however, do not worry as we said, this really is a test so likely just a couple of consumers are visiting them. We are unsure what you have to do to be able to be chosen for the exam, but if you do not own it, then you are not a part of it.
This might also not be the initial Facebook product/service to provide such safety measures. This past year, Facebook rolled out Face ID and Touch ID service for WhatsApp, offering up an identical way for consumers to protect themselves and their privacy by making certain they get to watch the messages that they get on WhatsApp.
