If you recall, Facebook has been testing the end-to-end encryption in Messenger earlier this year through a feature called Secret Conversations. Back then, Secret conversations was only available for selected users of the Facebook Messenger but today, Facebook has make it official for over 900 million users of Facebook to enjoy end-to-end encryption protection in the Messenger app.
In case you don’t know, End-to-end encryption/Secret conversations is a feature that make it possible for only you and the person you’re chatting with to have access to your chat messages, simply mean that not even Facebook can see what you’re talking about. This feature also made it possible for you to set time limits on messages sent through Secret Conversations, forcing them to expire and automatically delete after a pre-determined amount of time.
It will also be good for you to note that the End-to-end encryption in the Messenger app is not set on default, So if you like to enjoy this feature, you will have to turn it on manually and this can be done by tapping the information icon in the upper-right corner of existing or new conversations.
End-to-end encryption or Secret Conversations is available now in both the Android and iOS versions of Messenger, but if you’re not seeing it right away, double check to make sure Messenger has been updated – Secret Conversations are only found in the latest version of the Messenger app.
