Facebook rolls out ‘App Lock’ for Messenger to protect users’ privacy

Facebook on Wednesday announced new privacy and security features for Messenger including App lock, which enables users to add “another layer of security”.

With App lock, users can lock Messenger and it will require an authentication method like Face ID or Touch ID to open it.

“App Lock lets you add another layer of security to your private messages and helps prevent other people from accessing them,” said Jay Sullivan, Director of Product Management, Messenger Privacy and Safety, in a statement.

“…App Lock uses your device’s privacy settings like fingerprint or face authentication to unlock the Messenger app, and your touch or face ID is not transmitted to or stored by Facebook,” Sullivan added.
