"This message will self destruct" feature headed to Facebook Messenger
The information was delivered by Twitter outlet @iOSAppChanges, which published screenshots showcasing the feature as part of Messenger for iOS version 68.0. While this is the current version of the app available in the App Store, the functionality is apparently destined for a later build. Anyway, the feature lets users decide the lifetime of each message in minutes, days, months, even years. When the period expires, the message's recipient will no longer see its contents. The user is notified with a text below the message saying "You turned on disappearing messages," followed by the time they have left before they expire.
Additionally, Facebook is developing a "secret chat" feature for Messenger. The existence of traces of code linking to it was reported in March, and the functionality is supposedly available in Messenger for iOS version 67.0, in the form of a hidden feature.
iOS users aside, both additions should be brought to the Facebook Messenger app for Android and other platforms in the near future.
