After nearly five years of hard work, a period that included several regulatory hurdles, Meta has successfully advanced to the next stage in its rollout of default end-to-end (E2E) encryption in Messenger.


The update has entailed a complete rebuild of the app, integrating stronger privacy measures at its core, providing greater assurance to users that their private chats will stay private, no matter who may attempt to infiltrate them, Meta included.
As Meta explains:
“The extra security layer provided by end-to-end encryption ensures that the content of your messages and calls with friends and family are protected from the moment they leave your device until they reach the recipient’s device. This means that nobody, including Meta, can see what’s sent or said, unless you choose to report a message to us.”
The shift to full encryption by default brings Messenger more in line with WhatsApp, and was originally announced as part of Meta’s plan to amalgamate its various messaging tools to streamline cross-app communication. This eventually resulted in the development of a single, universal inbox containing all your Messenger, WhatsApp, and IG Direct chats, which you can access from each service.
In addition, all your Messenger chats will soon be encrypted, while Meta’s also adding new features to align Messenger more with WhatsApp’s functions.


Disappearing messages, like on WhatsApp, will last for 24 hours, and Meta’s also making it easier to see when disappearing messages are active in your chats.


Meta’s also added new read receipt controls and improved visual display options, along with variable playback speeds for audio messages, again similar to WhatsApp.
What’s encryption without Meta’s other new features?
But encryption is the major addition, and the one Meta has been fighting to enact despite opposing groups’ concerns that it could facilitate more criminal activity in Meta’s apps.
The U.K. Government has been one of the most vocal opponents.
