Meta, the parent company of Facebook, initiates the rollout of default end-to-end encryption for personal chats and calls on Messenger. Group chats will retain an opt-in feature for encryption. The move aims to enhance security and prevent access to chat content by Meta or third-party entities.

Years of development culminate in Messenger's comprehensive security update

Meta's Messenger undergoes a significant overhaul, taking years to implement end-to-end encryption. Rebuilding features like the sticker library and chat storage from the ground up was crucial for the rollout. The Signal protocol is employed for end-to-end encryption on Messenger, aligning with the company's commitment to user privacy.

Additional features introduced alongside encryption update

The security update is accompanied by new Messenger features, including the ability to edit messages within 15 minutes of sending, speed control for voice messages, enhanced photo and video layouts, and a new interface for disappearing messages. Meta also reveals plans to enable HD photo and video sharing on Messenger.
