Meta, the parent company of Facebook and Messenger, just announced that it is rolling-out end-to-end encryption on 1-on-1 chats and calls on Messenger. End-to-end encryption have always been available on Messenger but this roll-out the company is making end-to-end encryption on Messenger by default. End-to-end encryption means that only you and the other person you are sending the message to, can see the messages and calls, not even Meta can view them.

Loredana Crisan, Head of Messenger explains;

Since 2016, Messenger has had the option for people to turn on end-to-end encryption, but we’re now changing private chats and calls across Messenger to be end-to-end encrypted by default. This has taken years to deliver because we’ve taken our time to get this right. Our engineers, cryptographers, designers, policy experts and product managers have worked tirelessly to rebuild Messenger features from the ground up. We’ve introduced new privacy, safety and control features along the way like delivery controls that let people choose who can message them, as well as app lock, alongside existing safety features like report, block and message requests. We worked closely with outside experts, academics, advocates and governments to identify risks and build mitigations to ensure that privacy and safety go hand-in-hand.

Aside from the end-to-end encryption, new features have been introduce to Messenger like Editing messages that are sent, Set a message to disappear after 24 hours, read receipt control, photos and video upgrades, speed control on voice messaging and additional security technology to make the Messenger platform more secure.
