From CNET: Facebook on Wednesday rolled out two new privacy features for its Messenger platform. The features are designed to give users more control over who sees their chats and who can contact them.
First, App Lock allows you to use your device's privacy settings, such as fingerprint or face authentication, to unlock Messenger. The feature is designed to prevent anyone borrowing your phone from accessing your chats. It's currently available on iOS and is coming to Android in the next few months.
Facebook is also launching a new centralized section for privacy settings, where users will have easier access to App Lock, blocked people and more.
Additionally, the social network is working on new controls that allow users to choose who can directly message or call them, who goes to the message requests folder and who won't be able to message or call at all. Facebook will also be testing a feature that blurs images in the message requests folder, so users don't have to see images from people they don't know before replying or blocking or reporting an account.
