Facebook Messenger will soon enable facility to lock their messages on iOS. This will make the app more secure. Facebook is implementing the option to require Face ID and Touch authentication in order to access the user’s inbox with a future update. After enabling this feature users will need to re-enter their password, or engage Touch ID or Face ID before they can read messages. Users can also set time period after leaving the app for when they will need to re-authenticate.
“We want to give people more choices and controls to protect their private messages, and recently, we began testing a feature that lets you unlock the Messenger app using your device’s settings. It is an added layer of privacy to prevent someone else from accessing your messages” said facebook spokesperson.
Currently the company is testing the new security feature among a small percentage of Messenger’s iOS users, though it may in time be available more widely, including on Android.
