With App Lock, a new feature for Facebook's Messenger, users can choose whether device privacy settings such as the Face ID are required to unlock Messenger.


Facebook launched two new privacy features for its messenger platform on Wednesday. The functions are designed to give users more control over who sees their chats and who can contact them.

First, with App Lock, you can use your device's privacy settings, such as fingerprint or face authentication, to unlock Messenger. The function is designed to prevent people who borrow your phone from accessing your chats. It is currently available for iOS and will be available for Android in the coming months.

Facebook is also launching a new central privacy settings area where users can more easily access App Lock, blocked people, and more.

In addition, the social network is working on new controls that allow users to choose who can send or call messages directly, who can switch to the message requests folder, and who cannot make messages or calls at all. Facebook will also test a feature that blurs images in the message request folder so users don't have to see images of people they don't know before responding, blocking or reporting an account.

The social media giant has been criticized not adequately protecting user privacy increased concern across its platforms after the Cambridge Analytica scandal, in which the personal data of up to 87 million Facebook users was not properly accessed. Last year, Facebook found that millions of Instagram passwords were saved in plain text. According to reports, the company had collected email contacts from around 1.5 million users without permission for several years without permission. As the world's largest social network, Facebook controls data from more than 2 billion people.
