Facebook, by far the world’s largest social service, released a new feature to its Messenger app. Jay Sullivan, who is responsible for Messenger’s privacy and security, spoke about the new App Lock feature.
Application lock means that outsiders do not have access to Messenger's private messages. For example, if a family member picks up the phone, they won’t be able to watch your conversations. Messenger is unlocked with a fingerprint or face, for example. The feature will first be available on iPhone and iPad and will be coming to the Android version of Messenger within a few months. The feature can be found in Messenger's updated privacy menu.
However, it is worth thinking about implementing the feature twice, Gizmodo ponders. The immediate question is whether Facebook will once again try to get people to hand over their face or, in this case, their fingerprints of their privacy to a highly questionable company. And using security again as a tick.
This is exactly what Facebook has done in the past. When Facebook once asked its users ’phone numbers for two-step identification, those numbers were also used to target ads, among other things.

Another example relates to the European Union's general data protection regulation, which required companies to obtain permission from their users to process personal data. Facebook used this poll to get people to give their facial image to it.

Facebook’s Sullivan warrants that the touch or face used to unlock the app will not be passed on to Facebook, and Facebook will not store this information.
Messenger is also coming up with the ability to decide who can send messages or call the user directly, who goes to the waiting room, and who can’t communicate or call at all.
