Facebook has started launching additional security features for chat Messenger to render it impossible for anyone to read your conversations in the chat app, despite handing your phone to others.

Facebook utilized facial recognition technology to lock your Messenger chats via Face ID lock for iPhone and iPad users.

This added layer of personal information security is called App Lock, which gives the users “the confidence” to lend their phones to their family or friends without worrying that they’ll access your chats.

You can choose whether to lock the application with touch or Face ID.

For now, App Lock is only available to iOS users. Android users are expected to gain access to the feature soon.
