Meta Implements Default End-to-End Encryption for Messenger

Mark Zuckerberg’s Meta has initiated the widespread introduction of default end-to-end encryption for Messenger, bringing a significant security upgrade to personal chats and calls. While encryption for group chats remains optional, this move aims to enhance user privacy by preventing Meta and other third-party entities from accessing chat content.

The journey to implement end-to-end encryption on Messenger began in 2016 with a limited test of the “secret conversations” mode. Over the years, Meta progressively introduced encryption features, extending to voice and video calls in 2021 and group chats and calls in January 2022. The company tested end-to-end encryption for individual chats starting in August 2022 and committed to a default rollout by the end of 2023.

Default End-to-End Encryption for Messenger Features

Meta attributes the extended timeline for end-to-end encryption deployment to the meticulous rebuilding of Messenger features, including the sticker library and chat storage. The encryption protocol employed is based on the Signal protocol.

With this rollout, Messenger inches closer to achieving comprehensive end-to-end protection, aligning it with Meta’s other chat app, WhatsApp. Additionally, Instagram DMs are slated to receive end-to-end encryption following the completion of the Messenger rollout.

Alongside this security enhancement, Meta introduces several new Messenger features. Users can now edit messages within 15 minutes of sending, control voice message playback speed at 1.5x or 2x, and experience new layouts for photos and videos. The company is also developing the capability to send HD photos and videos on Messenger. As Meta continues to fortify the security and functionality of its messaging platforms, users can anticipate an enriched and more secure communication experience.

Meta has commenced the widespread implementation of default end-to-end encryption for its Messenger app, elevating security for personal chats and calls. While group chats retain optional encryption, this move underscores Meta’s commitment to user privacy by restricting access to chat content from both Meta and external entities. The deployment, based on the Signal protocol, follows years of meticulous reconstruction of Messenger features, including the sticker library and chat storage. With this upgrade, Messenger aligns itself more closely with Meta’s encryption-focused platforms, such as WhatsApp. Alongside this security enhancement, Meta introduces new Messenger features, including message editing, voice message speed control, and improved photo and video layouts.
